The resort isn't that big, but anywhere around Paty O's or the sexy pool would be the closest. When we were there, we had two different rooms, on opposite ends of the resort and neither of them were more than a 2 minute walk from the action!
Patty o's is nosier so if you don't plan to sleep in and you can sleep through anything then it is the perfect area to stay around. We usually do cause sleeping is a maybe 4-5 hour thing.
