Group and Event Travel in California

The biggest hotels in California start with Hilton San Francisco Union Square at 1921 rooms, followed by Manchester Grand Hyatt San Diego (1628 rooms) and Hilton Anaheim (1572 rooms), each offering enough capacity for large-scale group travel. These properties are built to host sizable teams, conferences, and events without dividing a group across multiple buildings. Travelers and the colleagues or coordinators who book on their behalf can search, compare, and reserve rooms at any of these hotels through Engine.

California's need for large-capacity hotels traces back to its scale as a state with heavy convention, conference, and corporate event traffic across its metros. The top properties on this list are spread across San Francisco, San Diego, and Anaheim, showing that the biggest bookable hotels are not concentrated in a single city. These hotels serve organizations of every size and industry, from a company sending a small team to one filling an entire room block for an event. Engine lists them alongside the rest of the state's inventory, with Engine Groups handling bookings of 9 or more rooms and self-serve booking for stays of 8 rooms or fewer.
