Unless they have changed this recently, all of the All-Stars rooms that are Disabled Accessible have King Beds.
Some of the Accessible rooms have walk-in showers and some have tubs with grab bars.
The accessible rooms at All-Star Movies are in Mighty Ducks and Fantasia. We have stayed/seen four of them in Mighty Ducks and they all were King Beds.
We have stayed in an Accessible Room in Touchdown at Sports and it was a King Bed.
We have stayed in an Accessible Room in Surfs Up at Sports and it was a King Bed.
Pop Century (also a value resort) has some accessible rooms with two doubles, but I'm pretty sure those rooms have a tub with grab bars.
Port Orleans FQ has at least one accessible room with two doubles, but it has a tub with grab bars.
