Short answer: Two winter costs are moving against exhibitors right now, and they are not the two people expect. Diesel is heading for a record while gasoline eases, and Las Vegas convention-week room rates are climbing through a soft tourism market rather than falling with it. Both are fixable, but only in advance. Neither is fixable in January.
Season starts in earnest the first week of the year. CES runs January 6–9, 2027 at the Las Vegas Convention Center, World of Concrete exhibits January 19–21, and the winter calendar fills in around them. Which means the decisions that determine what your winter shows cost are being made right now, in September, by people who mostly are not thinking about them yet.
Are fuel prices going up this winter?
Diesel is. Gasoline is not. That distinction is the whole story, because trade show freight moves on diesel and almost nothing else.
In its September 9, 2026 outlook, the U.S. Energy Information Administration expects retail diesel to average $5.55 a gallon in the fourth quarter of 2026, against a full-year 2026 average of $5.07 and a 2027 forecast of $4.40. Gasoline is going the other way: $3.84 a gallon for 2026, easing to $3.35 in 2027, as Brent crude falls from about $91 a barrel this year to about $74 next.
So a marketing manager filling up a rental car in January will notice fuel getting cheaper, and will be right. The freight invoice for the same trip will say the opposite, and will also be right.
The reason is inventory, not crude. The EIA expects U.S. distillate fuel oil stocks — the pool diesel comes out of — to fall below 100 million barrels in October for the first time since 2003, and to stay below the five-year low through the first quarter of 2027. A supply floor that low arriving at the same time as peak winter heating demand is what a record price looks like before it happens.
The number on your invoice depends on where the truck is
National averages hide the part that matters. In the week of August 31, 2026, on-highway diesel averaged $5.599 nationally — but that average is stretched across a spread of nearly two dollars.
| Region | $ / gallon | vs. U.S. average |
|---|---|---|
| California | $7.218 | +$1.62 |
| West Coast (PADD 5) | $6.497 | +$0.90 |
| Central Atlantic | $5.838 | +$0.24 |
| West Coast less California | $5.872 | +$0.27 |
| U.S. average | $5.599 | — |
| Midwest | $5.571 | −$0.03 |
| Gulf Coast | $5.360 | −$0.24 |
| Lower Atlantic | $5.276 | −$0.32 |
California is running $1.62 above the national average. That is not trivia. It is the number sitting inside every fuel surcharge on freight originating in, passing through, or repositioning out of California — which describes a large share of everything that arrives in Las Vegas. A Southern California origin is the most expensive diesel lane in the country, and it feeds the busiest winter show city in the country.
Two practical consequences. First, if you are comparing bids and one carrier is materially cheaper, check where the equipment is based before you assume you found a deal. Second, the fuel surcharge is an indexed pass-through on most contracts, so it is not something your logistics coordinator negotiated badly — it is a number that will move between quote and invoice. Ask what index and what week.
How much does cold weather reduce fuel economy?
More than most people would guess, and it applies to the sales team's rental cars and the crew's vans as much as to freight.
The federal fuel economy data is blunt about how much winter takes. A conventional gas vehicle's city fuel economy runs roughly 15% lower at 20°F than at 77°F, and drops as much as 24% on short trips of three to four miles. The full published ranges are worse.
| Vehicle | City driving loss | Short trips (3–4 mi) |
|---|---|---|
| Gas engine | 10% – 20% | 15% – 33% |
| Hybrid | 20% – 40% | 25% – 45% |
| Electric | ~39% (mixed) | Range down ~41% |
Short trips are the killer, and short trips are exactly what a show week is: hotel to hall, hall to dinner, dinner to hotel, over and over, with the engine never reaching operating temperature. If your team has rented hybrids on the assumption that they are the economical choice, be aware that hybrids lose proportionally more in the cold than gas engines do — 20% to 40% in city driving against 10% to 20%.
What is the best way to save fuel in winter?
Ranked roughly by how much they actually return, rather than by how often they get repeated:
- Combine trips. This is the largest single lever, because it attacks the cold-start penalty directly. Several short trips from cold burn dramatically more than one longer trip that lets the engine warm up. On a show week that means consolidating supply runs instead of sending someone out four separate times.
- Stop warming the engine up. Idling to warm up is close to pure waste — the guidance is to drive gently after about 30 seconds. Modern engines warm faster under light load than at idle. For freight the same arithmetic is far larger: a long-haul truck burns about 0.8 gallons an hour at idle, and across the fleet more than a billion gallons a year disappear into idling at rest stops, part of over six billion gallons of gasoline and diesel lost to idling annually.
- Check tire pressure, then check it again. Tire pressure falls about 2% for every 10°F drop — roughly 1 PSI per 10 degrees at normal passenger pressures, and about 2 PSI at the higher pressures commercial tires run. Across a typical 50-degree swing from summer to winter, that is around 5 PSI gone, which is enough to cost fuel and handling at once. Nothing on this list is cheaper to fix.
- Use the right oil. The manufacturer specifies a cold-weather grade for a reason. Thicker-than-specified oil in cold weather is a measurable fuel penalty for no benefit.
- Park inside. A vehicle that starts warmer stays out of the worst part of the penalty curve. If the crew has garage access at the hotel, that is worth more than it sounds.
- Take the roof rack off. Aerodynamic drag from accessories nobody is using is a permanent tax. Remove them when they are not in use.
- Go easy on the seat warmers and defrosters. Minor on a gas vehicle, significant on an EV. If anyone on the team is driving electric, preheating the cabin while still plugged in is the single best habit available — and it is free.
None of this is dramatic on its own. Together, across a crew running vans and rentals for a week in a cold city, it is the difference between a travel line that lands where you budgeted it and one that runs 20% over for reasons nobody can point at afterward.
The freight decision that outranks all of them
Everything above trims a cost. This next one removes a risk, and in winter the risk is the expensive part.
Weather is the variable most exhibitors price at zero right up until it costs them a show. A booth that arrives late is not a discount — it is a booth that does not exist, at a show you have already paid for. instead of direct-to-show takes the weather out of the critical path, because a shipment that arrives days early absorbs a storm, a closed pass, or a lost day without anyone finding out.
are the worst thing to gamble on, because they are the one component that cannot be substituted on site. A missing upright can be improvised. A missing header cannot — and reprinting in the show city on a Tuesday costs several times what producing it on schedule would have.
And the cheapest way to survive a bad diesel winter is to not put freight on the road at all. removes the long-haul leg altogether: no cross-country fuel surcharge, no weather exposure, no transit window to protect. For an exhibitor doing one or two winter shows, that arithmetic has rarely looked better than it does going into 2027.
Do Las Vegas hotel rates drop when tourism is down?
This is where most people's instinct is exactly wrong, and it is worth being precise about, because acting on the wrong version of it is expensive.
Strip average daily rate went up anyway — to $216, from $201 a year earlier. Strip RevPAR rose to $179 from $171.
The reason is in the same report. Convention attendance in January 2026 rose 7% to 672,100, with CES drawing 148,000, World of Concrete 58,000, and SHOT Show 53,000. Leisure demand and convention compression are two different markets sharing one set of buildings, and in January the second one wins.
Compare that January Strip rate against the same city in summer: $156.32 average daily rate in June 2026, $157 in July. The winter show-week premium runs roughly 38% above the summer number, in a year when the tourism headline was negative both times.
So the honest version of "book now because business is down" is this: a soft market is not going to hand you a January discount, because January was never sold to leisure travelers in the first place. What booking early buys you is not a distressed rate. It is the block rate — which is the only below-market number available in show week — and the ability to hold it before the cutoff date takes it away.
How far in advance should I book hotels for a trade show?
For an individual, as early as you are willing to commit. For a group, the question is the wrong shape: it is not a number of weeks, it is a date on a contract.
Three terms govern the whole thing, and most exhibitors who get burned got burned by not knowing one of them.
The cutoff date is when the hotel returns unsold rooms from your block to general inventory. After it passes, your people pay whatever the market is charging — and in Las Vegas in January, we just established what the market is charging. The cutoff, not the show date, is your actual deadline.
The attrition clause is the penalty for booking a block you do not fill. Typical terms require you to pick up 80% to 90% of contracted rooms; below that, you pay for the shortfall, usually at a percentage of the room rate for each unfilled room night. Fifteen unfilled rooms at $200 apiece is $3,000 you owe for rooms nobody slept in.
The release clause is the escape hatch, and it is the one people forget to negotiate. It lets you hand rooms back before the cutoff without penalty. With a real release clause in the contract, booking a generous block early stops being a gamble — you take the rooms while they are cheap and shed what you do not need while it is still free to do so.
That combination is the answer to "how early." Book the block early enough to get the rate, negotiate a release clause so that early booking carries no downside, and put the cutoff date in your calendar the day you sign — not the show date. Then chase your own people to book inside the block, because attrition is charged on rooms your team booked somewhere else just as surely as on rooms nobody booked at all.
One more thing about that block: guard it
Room block poaching is a real and prosecuted problem, not a rumor. An unaffiliated company emails your team claiming to represent the show's housing bureau, frequently insisting the official block is sold out, and takes bookings — sometimes for rooms it does not hold, sometimes charging cards for reservations that do not exist. A 2018 Events Industry Council survey found 43% of respondents affected by fictitious reservations and credit card fraud, and industry estimates put the scale at roughly 15 million bookings a year.
In January 2018, a federal court in the Northern District of Georgia awarded the U.S. Poultry and Egg Association $749,797.50 in damages and fees against a travel agency that had emailed IPPE exhibitors and attendees falsely claiming to represent the show.
The defense is simple enough to put in a one-line email to your team: book only through the housing link on the official show website, and treat any unsolicited message about show hotels as false until proven otherwise — particularly one that says the block is full. If somebody asks for payment before confirming a reservation, that is the end of the conversation.
What to do this month
- Book winter blocks now, with a release clause. The rate is better in September than it will be in December, and a release clause removes the reason to wait.
- Put the cutoff date in the calendar, not the show date. That is the day the rate disappears.
- Ask carriers which fuel index they use, and for which week. Diesel is heading into a record quarter. You want to know how the surcharge is calculated before it lands, not after.
- Book advance warehouse, not direct-to-show. Winter is the season where the difference stops being theoretical.
- Send one email about housing scams. Official link only. It costs you five minutes.
- Price a regional rental against shipping your own. With California diesel at $7.22, the comparison is not what it was two years ago.
The wider point
Almost everything expensive about winter show season is a scheduling problem wearing a cost problem's clothes. The diesel surcharge, the January room rate, the emergency reprint, the expedited freight — every one of them is the price of making a decision late. None of them can be negotiated down in the week of the show, and all of them can be substantially avoided in September.
The industry is under enough real margin pressure without paying the late fee on top of it.
FAQ
Are fuel prices going up this winter?
Diesel is. Gasoline is not. The EIA forecasts retail diesel to average $5.55 per gallon in the fourth quarter of 2026 because U.S. distillate inventories are expected to fall below 100 million barrels in October for the first time since 2003 and stay below the five-year low into 2027. Retail gasoline is forecast at $3.84 per gallon for 2026, easing to $3.35 in 2027. Trade show freight rides on diesel, so the surcharge line is the one that moves.
How much does cold weather reduce fuel economy?
A gas vehicle loses roughly 15% of its city fuel economy at 20 degrees Fahrenheit compared with 77 degrees, and as much as 24% on short 3 to 4 mile trips. Hybrids lose 20% to 40% in city driving. Electric vehicles lose about 39% in mixed driving, with range down about 41%.
What is the best way to save fuel in winter?
Combine trips so the engine runs warm more of the time, stop idling to warm up and instead drive gently after about 30 seconds, check tire pressure monthly because tires lose roughly 1 PSI for every 10 degree drop in temperature, park indoors where possible, use the manufacturer cold-weather oil grade, and remove roof racks when they are not in use.
How far in advance should I book hotels for a trade show?
For a group, before the housing block cutoff date rather than by a fixed number of weeks. The cutoff is the date the hotel returns unsold block rooms to general inventory at prevailing rates. Book the block early, then use the release clause to shed rooms you do not need before the cutoff, which avoids attrition penalties on unfilled rooms.
Do Las Vegas hotel rates drop when tourism is down?
Not during convention weeks. In January 2026 Las Vegas visitation fell 2.2% year over year, yet Strip average daily rate rose to $216 from $201, because convention attendance climbed 7% to 672,100. Soft leisure demand and convention week compression are separate markets, so a weak tourism headline is not a reason to expect a discount in show week.
What is hotel room block poaching?
An unaffiliated company contacts exhibitors claiming to represent the show housing bureau, often saying the official block is sold out, and takes bookings or payment for rooms it may not hold. In 2018 a federal court awarded the U.S. Poultry and Egg Association $749,797.50 against one such operator. Book only through the housing link on the official show site.
