Why Las Vegas Keeps Winning the Convention Wars: It Comes Down to Hotel Rooms

The 2025 scoreboard: Vegas at #2, but hotels tell the real story

In its 2025 rankings, meetings-industry platform Cvent named Las Vegas the second-best convention destination in North America, trailing only Orlando, which has held the top spot for over a decade. Chicago rounded out the top three.

But the headline ranking hides a more interesting detail. When Cvent ranked the individual host hotels — the properties actually landing and running big conventions — three Las Vegas resorts made the continent’s top 10: The Venetian at #3, Fontainebleau Las Vegas at #5, and Wynn and Encore Las Vegas at #7. Orlando, the city that took the #1 spot overall, placed zero hotels in that top 10.

Cvent built these rankings from more than $20 billion in global sourcing and request-for-proposal activity run through its platforms in 2025, so this is not a popularity contest. It reflects where meeting planners are actually spending money and booking rooms.

Why the hotel room math decides everything

Here is the pattern playing out across the country right now: mid-sized convention cities are spending hundreds of millions of dollars to add hotel rooms, because a shortage of rooms is the single thing holding them back from landing bigger events.

Detroit is a clear example. Even before finishing its new 25-story JW Marriott convention hotel, the city is already planning a second 600-room, $450 million hotel next to its Huntington Place convention center. The head of Visit Detroit called the room shortage the city’s “Achilles’ heel” — the thing preventing it from landing the country’s most prominent conventions. Raleigh is advancing a 29-story, 600-room convention hotel. Pittsburgh is adding a 500-room hotel next to its convention center. West Palm Beach and Columbus are pushing similar projects. The common thread: room inventory is the bottleneck, and everyone is trying to catch up.

Now put that next to Las Vegas. The city offers more than 150,000 hotel rooms — the MGM Grand alone has over 7,000. Cvent counts 291 qualified hotel venues, 300 special event spaces, and 4.6 million square feet of combined meeting and convention space in the city. While other destinations demolish city blocks to add a few hundred rooms, Vegas already operates at a scale no one else can match. That is exactly why Las Vegas keeps winning the shows that need tens of thousands of rooms at once, like CES and SEMA, and the rest of the calendar that fills the city several times a year.

What this means if you are attending a Las Vegas show

The convention-wars story is good news and a warning at the same time.

Booking during a big show? Compare rates across LVCC-area hotels on Hotels.com — the earlier you lock a room, the more of that 150,000-room inventory is still in play.

The good news: with 150,000+ rooms, Las Vegas rarely runs out of options entirely. Even during a massive show, you can almost always find a room somewhere in the city.

The warning: the rooms that matter, the ones close to your venue at a reasonable rate, still sell out fast during major shows. Vegas has scale, but demand during peak weeks (CES in January, SEMA and AAPEX in early November) overwhelms even 150,000 rooms near the convention center. That is why the properties within walking distance of the LVCC are booked months ahead. The city’s massive inventory protects you from being completely shut out, but it does not protect you from overpaying or commuting 30 minutes if you book late.

The bottom line

Las Vegas wins conventions because it solved the hotel-room problem decades ago, while other cities are only now spending billions to catch up. For attendees and exhibitors, that scale is a safety net, but not a substitute for booking early. The best rooms, at the best rates, near the right venue, still go to the people who plan ahead.

Frequently Asked Questions

Is Las Vegas the top convention city in North America?

Las Vegas ranked #2 for 2025 according to Cvent, behind Orlando. However, three Las Vegas resorts (The Venetian, Fontainebleau, and Wynn and Encore) placed in the continent’s top 10 convention host hotels, while no Orlando hotel did.

How many hotel rooms does Las Vegas have?

More than 150,000, the most of any U.S. convention destination. The MGM Grand alone has over 7,000 rooms. Cvent counts 291 qualified hotel venues and 4.6 million square feet of combined meeting and convention space in the city.

Why are other cities building convention hotels?

Cities like Detroit, Raleigh, Pittsburgh, and West Palm Beach are adding convention hotels because a shortage of rooms near their convention centers prevents them from landing large events. Room inventory is the main bottleneck for growing convention business.

If Las Vegas has so many rooms, do I still need to book early?

Yes. Despite 150,000+ rooms, the hotels closest to the venue at reasonable rates sell out months ahead during major shows like CES and SEMA. The city’s scale keeps you from being shut out entirely, but the best rooms still go fast.
