Hi, Latasha!
Let me give you a proposed itinerary that you can start with. If this does not work for you, move some things around, or let me know how we can fix it! I do not know how many park days you have, which may change your strategy a bit. But, this should get you started!
8/15: Arrival day, La Nouba/Downtown Disney
8/16: Epcot/break/end day with Fantasmic! at Hollywood Studios
8/17: Hollywood Studios/break/end day with Wishes! at Magic Kingdom
8/18: Water Park by day, DisneyQuest by night
8/19: Animal Kingdom/late afternoon water park
8/20: Hollywood Studios/break/end day with Illuminations at Epcot
8/21: Magic Kingdom
8/22: Time to go home, see ya real soon!
Is this sort of what you are thinking of? This will give you all 4 parks, 2 water park visits, 1 DisneyQuest visit, along with your La Nouba reservation.
Play with this schedule! Add/delete times for "must see" parks, add water park time, or whatever appeals to you. Once you have a schedule you are happy with, make some
Advance Dining Reservations that will fit into your itinerary. Hope this helps. If not, let me know!
