We also just returned from OKW and we were in building 23. We liked this location since we were close to the main pool and store. We did not have a car, and it seems to me that it would be pretty inconvenient to stay in the buildings in the back of the resort if you wanted to go to the main pool, store, or Olivia's. Another thing I noticed is that the buses turn around right in front of some of the buildings like 20, 51 and 52. Those that have stayed in those buildings can correct me if I'm wrong, but I would think that those would be a lot noisier and busier, plus a little less safe for younger kids since the buses go right by the parked cars.
