It depends on what you are looking for really. If you want to be close to a pool, the main building, or to be in a quiet area, then you would request something different. The first time I stayed there I had just about the perfect location for me. It was a high floor room on the back side of the Surfs Up building. It was close to the main building, had a great view of Summit Plummet at Blizzard Beach and was quiet as it was on the car park side of the building.
Obviously you can't be too specific with requests, but if you decide what is the most important factor for you, there should be no probs as long as it isn't too busy.
