Frequently asked questions
How do I book a block of rooms at one of Chicago's bigger hotels for a company event?
If you need 9 or more rooms, Engine Groups handles the booking for you. For 8 rooms or fewer, you can search and book self-serve on the platform. Properties like Palmer House a Hilton Hotel (1641 rooms) and Hyatt Regency McCormick Place Chicago (1258 rooms) can accommodate group stays.
What makes a hotel one of the biggest in Chicago?
Room count is the main measure. Palmer House a Hilton Hotel leads the list with 1641 rooms, followed by Hyatt Regency McCormick Place Chicago at 1258 rooms and Sheraton Grand Chicago Riverwalk at 1218 rooms. Hotels with many rooms tend to offer the capacity and facilities that work well for groups or events.
Are Chicago's bigger hotels only for groups, or can individual business travelers book them too?
Individual business travelers can book any of these properties. Hotels with hundreds of rooms often have amenities that serve solo guests, like on-site dining, fitness centers, and business services. You're booking the same inventory whether you need one room or twenty.
How far ahead should I book if my team needs a lot of rooms at a hotel in Chicago?
For a group stay, three to six months in advance is a good baseline, especially during busy seasons or if you're targeting a specific property. Booking early helps ensure availability and gives you time to coordinate logistics. Engine Groups works with you when you need 9 or more rooms.
What should I look at when comparing big hotels in Chicago for my team?
Start with location relative to your meeting venue or office, then check room count and whether the property fits your group size. On Engine, you can compare pre-negotiated rates, review amenities, and see consolidated invoicing options. Look at proximity to transit and airports, and confirm the hotel can handle your booking window.
