Hotel pick in Orlando for GREATNESS? Ritz, JW Marriott, World Center, Omni, or Hyatt Reg Grand Cypress?

With these hotels listed, which do you think is the finest for POOLS with elementary age children, great food/restaurants/coctails, cleanliness!!!, updated rooms, 24hr roomservice, bars/grill at pool, really nice rooms? Does not have to be next to Disney, but near/easy route. Too hard to pick from so many great hotels in area. Going end of Aug 08.
