Frequently asked questions
How do I book a large block of rooms at one of the biggest hotels in St. Louis?
For a stay of 9 or more rooms, Engine Groups handles the booking at properties like Marriott St. Louis Grand (917 rooms) or Hyatt Regency St. Louis at The Arch (910 rooms). For 8 rooms or fewer, you can search, compare, and book self-serve on the platform.
Why choose a large hotel like Marriott St. Louis Grand for a work trip?
A bigger hotel can accommodate an entire team under one roof, simplifying logistics for meetings, group arrivals, and coordination. Properties with hundreds of rooms often have onsite amenities and meeting space (varies by property), so everyone stays close to where they need to be. It makes managing travel smoother when the whole group is in the same place.
How far ahead should I book when my team needs multiple rooms at a St. Louis hotel?
The earlier you book, the better your chances of availability, especially at high-capacity properties like Hyatt Regency St. Louis at The Arch (910 rooms) or Hilton St. Louis at the Ballpark (671 rooms). For large groups, start the process as soon as dates are confirmed to access the widest selection and pre-negotiated rates.
What should I compare when deciding between large St. Louis hotels for my team?
Room count matters, but also consider location relative to your meetings or the airport serving St. Louis, onsite amenities, and available meeting space if your trip includes group sessions. Engine lets you compare rates and property features side by side, so you can weigh capacity, cost, and convenience in one place.
How does billing work when I book a lot of rooms through Engine?
Engine offers consolidated invoicing, so you get one invoice covering multiple bookings instead of managing separate charges. You can choose from multiple payment options, and there is no membership fee to use the platform.
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.
