We stayed in Building 6 last spring break and it was fine except beware ot the LOUD noise as people come into work about 6am. I am an early riser so it did not bother me as I like to walk early to get a great spot at the pool and exercise. It is the farthest from the shuttles but not a big deal at all unless you have lots to carry. I think I would ask for building 2 over the pool or resort view due to the noise.
Just beware of the biuildng 2 units which are adjacent to the tunnel. We stayed in unit 2741 and it was a bit noisy in the morning as well.
