Group and Event Travel Across the USA

The Venetian Resort in Las Vegas, NV tops this list of the biggest hotels in the USA that you can book through Engine, with 4028 rooms. The Palazzo at The Venetian in Las Vegas, NV (3064 rooms) and Gaylord Opryland Resort & Convention Center in Nashville, TN (2888 rooms) round out the top three. Teams booking large blocks of rooms for conferences, corporate events, and multi-day meetings use this list to find hotels with the capacity to hold everyone under one roof.

Large-capacity hotels matter most when a conference, corporate event, or company gathering needs to place many travelers in one building without splitting the group across multiple properties. Room blocks of this size come up for organizations of every size and industry, from small teams booking a handful of rooms to larger groups filling hundreds. These biggest hotels in the USA tend to cluster in places like Las Vegas, the Orlando theme park area, Atlantic City, and other cities known for hosting conventions, since that is where demand for high room counts is steadiest. Engine lists these properties alongside the rest of its hotel network, and for a stay of 9 or more rooms, Engine Groups handles the booking, while stays of 8 rooms or fewer can be booked self-serve on the platform.

Frequently asked questions

How does billing work when I book multiple rooms at one of the largest hotels through Engine?
Engine provides consolidated invoicing, so you receive one invoice even when booking multiple rooms or properties across different cities. You can choose from multiple payment options, and there is no membership fee to use the platform. This makes it straightforward to manage expenses for large bookings or travel across several locations.
What's the best way to compare the largest hotels in different cities when planning where to send my team?
You can search and compare these hotels on Engine by filtering for the cities you're considering and sorting by room count or other criteria that matter for your trip. The three properties that lead the list are The Venetian Resort in Las Vegas (4028 rooms), The Palazzo at The Venetian in Las Vegas (3064 rooms), and Gaylord Opryland Resort & Convention Center in Nashville (2888 rooms). Comparing rates, location, and capacity side by side helps you decide which property fits your team's needs.
Where are most of the largest hotels in the United States located?
The properties with the highest room counts tend to concentrate in Las Vegas, the Orlando theme-park resorts, and Atlantic City. You'll also find large properties attached to convention centers in cities across the country. These locations typically have the infrastructure to accommodate hundreds of guests under one roof.
How far ahead should I book if my group needs a large block of rooms at one of these hotels?
Booking early gives you better access to availability and rates, especially at properties with thousands of rooms that host conventions and groups year-round. For a stay of nine or more rooms, Engine Groups handles the booking; for eight rooms or fewer, you can book self-serve on the platform. Starting your search several months in advance is a good practice for large room blocks.
Can individual business travelers book these large hotels, or are they only for groups?
Individual business travelers can absolutely book any of these hotels on Engine. Properties with high room counts often have the amenities and services that work well for solo travelers, including multiple dining options, business centers, and flexible check-in. You don't need to be part of a group to take advantage of the capacity and convenience these hotels offer.
