I think it's closest to 14, but not far from 27 either. The main pool is on an island and you have to cross a bridge to get to it. I believe there are 3-4 bridges from different directions. I always crossed from the main building which is closer to building 14. That building is a prefered building and we were not booked as prefered. Building 16 turned out to work well as we could cut accross the parking lot to the bus depot in the mornings. It still wasn't to far from the main pool either. The paths can get a bit confusing, but by the 2nd night we had our route down. If you are looking to be closer to the main building and main pool, I'd go for building 14. But honestly any building in that cluster is going to serve you well. If building 27 were closer to the main pool, it would be farther from the main building than 14-16. You might also want to know there are no elevators in Allagator Bayou, so if that's an issue, request a first floor room.
