Group and Event Travel in Washington
Hyatt Regency Seattle leads the biggest hotels you can book in Washington through Engine, with 1260 rooms. Sheraton Grand Seattle (1236 rooms) and The Westin Seattle (891 rooms), both also in Seattle, round out the top three. These large properties give teams the capacity they need for conferences, group trips, and events, and they serve organizations of every size and industry.
Seattle hosts a steady flow of conferences, conventions, and corporate events, and that demand is part of why Washington's biggest hotels, all located there, carry room counts in the thousands. Companies planning multi-day meetings or bringing large teams together need hotels that can hold that many travelers at once, and these properties are built for it. The hotels on this list serve organizations of every size and industry booking room blocks, from small teams to large group trips. Engine lists these properties alongside the rest of the state's inventory, with Engine Groups handling bookings of 9 or more rooms and self-serve booking available for 8 rooms or fewer.
Frequently asked questions
How do I book a large block of rooms for a company event in Washington?
If you need 9 or more rooms, Engine Groups handles the booking for you. For 8 rooms or fewer, you can search, compare, and book directly on the platform. Either way, you get access to pre-negotiated rates and consolidated invoicing across your stay.
Why choose a bigger hotel for a statewide conference in Washington?
A large property like Hyatt Regency Seattle (1260 rooms) or Sheraton Grand Seattle (1236 rooms) can house your entire group under one roof, simplifying logistics. Bigger hotels often have more meeting and event space, multiple dining options, and the capacity to handle arrivals and departures for large teams without strain.
What amenities can I expect at the largest hotels in Washington?
Large hotels typically offer meeting rooms, event space, on-site dining, and parking, though specifics vary by property. Properties like The Westin Seattle (891 rooms) often include fitness centers, business services, and flexible spaces that can accommodate both groups and individual business travelers.
Are Washington's biggest hotels only for groups, or can individual business travelers book them too?
These hotels work for both. While properties like Hyatt Regency Seattle and Sheraton Grand Seattle have the capacity for large events, they also serve individual business travelers who want reliable amenities, central locations, and the convenience of a full-service property.
How does billing work if I book rooms at multiple large hotels across Washington?
Engine offers consolidated invoicing, so you get one invoice even when booking across different properties or cities. You also have multiple payment options and no membership fee, which simplifies accounting for recurring travel or multi-city trips throughout the state.
Why don't you show rates for these hotels?
Hotels give Engine rates they only allow us to show business travelers, so a public page cannot list them. Create a free account with your work email to see them.
Is Engine free?
Yes. An Engine account is 100% free and without commitment, and you can leave anytime. Sign up with your work email.
