AAA's criteria is weak and vague. A Disney hotel with a pool with an empty bin where the towels should be gets the same rating as a hotel with a pool concierge and valet where they escort you to the chaise of your choice and wrap it in 3 towels and a 4th to dry yourself, and 2 different pitchers of complimentary citrus (Lemon/lime, Orange/Tangerine) ice water.The AAA ratings aren't subjective ratings. They're just a list of very clear things you need to do. Have room service, have sheets with x thread count, spend x dollars per room, have a restaurant with median dish price of x dollars, etc. If you check every box, you get the rating. It means that every single resort that's planned as a 4 Diamond will become a 4 diamond.
I know what a 4 star hotel is and Disney only has one domestic hotel that even comes close. And The Grand Californian isn't quite there.
