My mom and sister went to WDW last year and stayed at POP. They made oatmeal every morning that they brought from home. I know they have the hot water but I'm not sure about the bowls. I don't see why they wouldn't give you any if you asked though.
Yep we brought disposable bowls from home, or you could bring one bowl from home and wash it each day- but you know your not supposed to do laundry or dishes on vacation
