I don't have experience with AOA but you can usually find bottled water at the resort gift shops. They don't have big displays of it, usually 2-4 packs hidden somewhere in the bottom of the refrigerator. They sell it in 8 packs for around $4-5. If you don't see it, ask a CM. Sometimes they have to show me where it is. Can usually get an AP discount on it too, if you have one.
