I would strongly suggest staying elsewhere until the hotel abandons their recent decision to use motion sensing thermostats. I have stayed at this property several times in the past few months and each time I have had to spend significant time fighting with maintenance to disable the motion sensing feature on the thermostat.
When you pay for a +$250 night room you expect to have good air conditioning, right? Not at the St. Kitts Marriott. The rooms are set to 78-79 degrees until you enter and then they start cooling. It can take 2-3 hours for the room to cool down. This would be fine if you were always in your room but like myself, I'm sure you want to spend time outside your room.
Here is the worst part - when you are sleeping, the system thinks you are out of the room and will shut off so you wake up sweating every hour. Multiple complaints/calls to the managers haven't fixed this problem.
If it weren't for this issue, the property is nice. However, who wants to stay in a hotel without air conditioning?
