We had room 2723 and it was wonderful. From the food court the buildings go 14, 18, then 27 in a semi-circle. I found 27 convenient to everything... 2 minute walk to the food court, 3-4 to the bus stop, and maybe 5 to the pool. It was the perfect room for us. We had a trundle bed, and although we didn't ask for it we were so happy we had it. DH is normally a bed hog, so put him in a double bed and forget about sleeping. So DH had 1 bed to himself, I shared with 1 of the kids, and the other slept in the trundle. The kids rotated the trundle every couple of nights.
I'm glad we didn't have Bldg 14 as everyone has to walk by some part of the bulding to get to another bldg. Part of 18 is a smoking bldg so we didn't want that either. IMO Bldg 27 is a great choice.
