Frequently asked questions

What makes a hotel one of the biggest in Detroit?
The biggest hotels you can book in Detroit typically have several hundred rooms or more. Detroit Marriott at the Renaissance Center leads the list with 1328 rooms, followed by The Westin Book Cadillac Detroit with 453 rooms and Hollywood Casino at Greektown with 400 rooms. Hotels of this size can accommodate large groups, recurring travel, and events under one roof.
How far ahead should I book if my team needs a block of rooms at a big Detroit hotel?
For a stay of 9 or more rooms, Engine Groups handles the booking, and starting early gives you better availability at properties like the Detroit Marriott at the Renaissance Center. For 8 rooms or fewer, you can book self-serve on the platform. Booking several weeks in advance is a good baseline, though exact timing depends on the hotel and the dates.
How do I compare large hotels in Detroit when choosing where to send my team?
You can search and compare these hotels on Engine by filtering for room count, location, and amenities. Look at proximity to the airport serving Detroit, access to the areas your travelers need to reach, and whether the property offers meeting space or other features your group requires. Pre-negotiated rates and detailed property information make it easier to weigh your options.
How does billing work when I book rooms at a large hotel through Engine?
Engine offers consolidated invoicing, so you receive one invoice even when booking multiple rooms or repeat stays. You have multiple payment options, and there is no membership fee. This setup simplifies expense tracking and reconciliation for travel managers handling groups or frequent bookings.
Can individual business travelers stay at these big Detroit hotels, or are they only for groups?
These hotels work well for both groups and individual business travelers. A solo traveler can book a room at the Detroit Marriott at the Renaissance Center or The Westin Book Cadillac Detroit just as easily as a coordinator booking for a team. The same pre-negotiated rates and booking platform apply whether you're reserving one room or many.
