Biggest Hotels in the USA

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.

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.

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.

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.

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.
