My order is
1. Music (most peaceful, and best landscaping, least garish of the Values, new food court, no bus problems)
2. Movies (If you have to have giant Icons staring at you at least they are from Disney movies (although the Dalmatians creeped me out, good food court, no bus problems)
3. Sports (on the rare occasion that you share, it's the first stop, also had the best service in the Food Court of any of my stays)
4. AofA (Nice theming but not on my revisit list. crowded, loud, lousy bus service, food court was okay, I hated the showers in the standard rooms dark and cave like, literally painted to look like underwater cave, Giant Ursula creeped me out)
Haven't stayed at POP (will next month) but don't see it bumping Music from my top spot.
People will say that the allstars share buses. They do, sometimes, not often and usually only during the slow hours in the afternoon. I'm telling you I have almost never shared a bus at the Allstars. POP and AofA don't share but they are both huge resorts with only one bus pickup so it can be crowded or you wait for multiple buses. Both have their down points. Don't let bus service sway your choice. Go with theme and look at the Menus. That's the best way to choose between Values.
