AoA pretty much as the best of everything. Best pool, best food court, great transportation and a great location. The only real con is the standard rooms are priced a few bucks a nigh higher than the other values and are in a somewhat bad location.
The suites, while pricey are great for larger families.
Pop has nearly all the advantages of AoA save for the pool suites and food court. If you don't care about the pool or the suites, I would probably go with Pop over AoA especially if you want a room close to the lobby. food court and transportation.
The All Stars are pretty much all the same save for a redone food court at Movies and Music. I am not positive if it has been remodeled at Sports as of yet. I do however tend to stay away from Sports as that is where most youth athletic leagues tend to stay.
