I have a family of 5 with kids 8, 6, and 5 yrs old. Wanted to visit the Cayman Islands, but when I went to book the trip it said that you could only have 4 people per room. Would Marriott make me get a 2nd room for my young kids? Doesn't seem like there are many options for families over 4 out there with Marriott.
PINGREEMAN is right - sometimes you have to call. We've found that, after 9/11, a number of taller hotels (specifically in NYC) changed - OK, decreased - their capacities for certain rooms (on the web page) for a number of rooms. I have no idea how prevalent this practice is, but - again - it's definitely worth a phone call!
