I was at WDW in August, and stayed at Pop for 11 days. I regularly ate at the AoA food court, and rode both Pop and AoA busses to get home. Another thing I liked is that, at least at most of the parks/places the AoA bus stop was right next to the Pop bus stop. This allowed me to just snag the first bus that came along, or ride the less crowded bus home if both were there.
It's less then a 10 minutes walk to get to AoA from Pop, if you go across the Generation Gap Bridge (or whatever they are going to name it...on AoA's map, it has no name yet.
