Never been in person, but the AoA suites seem cramped per room, like how could all of you hangout in the living room with the kitchenette and closet in there? OKW is as big as a house, plus the pools are great too. I would guess you would have a shorter walk to your room in OKW from the bus since there are multiple stops in the resort. I recommend Turtle Pond area or if you're renting points, you can request close to Hospitality House.
All-Star Music has lovely family suites and the resort is much smaller than Pop or AoA for buses. Supposedly they are all renovated and have the same pull-down table bed, plus the new Murphy bed behind the sofa. We have 2 rooms at Movies in January but we think we are moving to the Family Suites instead since we won't have to do the sofabed thing.
They don't share buses unless it's the middle of the day and only 3 people are at the bus stop. Definitely less lines and less of a walk to your room. 3 food courts within the All-Star complex plus 6 pools to spread around too.
