For a stay of 9 or more rooms, Engine Groups handles the booking, and you should reach out as early as possible to secure availability and rates. For 8 rooms or fewer, you can book self-serve on the platform, and a few weeks' notice is often enough. Booking early is especially important during busy periods or when your dates coincide with conventions or local events.
