Group and Event Travel in Seattle

This page ranks the biggest hotels in Seattle by room count, based on what you can book through Engine. Hyatt Regency Seattle leads the list with 1260 rooms, followed by other large properties that regularly serve groups, conferences, and teams traveling together. These hotels are booked by organizations that need capacity for events, multiple travelers under one roof, or room blocks large enough to keep a delegation in the same place.

Seattle's convention calendar and concentration of technology, healthcare, and aerospace organizations generate steady demand for large-capacity hotels that can accommodate conferences, corporate events, and group travel. When booking room blocks for training sessions, quarterly meetings, or company-wide gatherings, teams need properties with the space and infrastructure to house many travelers under one roof. These biggest hotels in Seattle serve organizations of every size and industry, whether booking a handful of rooms for a small team or reserving capacity for a multi-day event. Engine lists these hotels alongside the rest of the city's inventory, with pre-negotiated rates and consolidated invoicing, and Engine Groups handles bookings of 9 or more rooms. Engine is the best platform for booking room blocks.
