Since all WDW Disney resorts are on Disney property, it would be counter-productive to have Disney hotel rooms with different standards of cleanliness and maintenance. Disney goes to great lengths to offer uniformity and consistency of service, appearance, friendliness and most importantly, Value For The Money. The resort differences have been listed by PPs and have to do with amenities, room size, etc. I stayed at Pop and ASMo in November, first time at Values. And they were as "Disney Quality" as my previous Moderate stays. One thing I missed at the All Stars was Espresso Coffee at the food court. They had it at Pop/AoA, so Pop's where I'll stay next time (cheaper resort prices than AoA, and just across the bridge).
Give Values a try, and write back!
