We stayed at POFQ last year for the first time. It is so beautiful there! I am sure you will love it. The grounds are lovely, the room was nicely decorated and so clean, and the pool (while crowded), was so fun!
I don't think there is a building there that would make it a long walk to anywhere. The resort is quite compact for a mod. Still, ask to be in building 5 - we were in this one. It was right next to the check in building and just down a short street and around the corner from the pool. Very convenient resort.
Don't pay more for a preferred view. The mods have no balconies from which to enjoy the view. Keeping your window drapes open to see it will only allow you to see all the people walking by. Not worth extra $$.
