Kristy,
Glad to help! Let me give you what park I would visit on what day, and one table and one counter service recommendation, per day. That should get you started!
- July 8 - Arrival Day
- July 9 - Magic Kingdom (Table: 'Ohana / Counter:Pecos Bill Tall Tale Inn & Cafe)
- July 10 - Hollywood Studios (Table: 50s Prime Time Cafe / Counter: ABC Commissary)
- July 11 - Epcot (Table: Chefs de France / Counter: Tangierine Cafe)
- July 12 - Magic Kingdom (Table: Whispering Canyon Cafe / Counter: Columbia Harbor House)
- July 13 - Animal Kingdom (Table: Tusker House / Counter: Flame Tree BBQ)
Note that for the Magic Kingdom table service restaurants I actually list resort restaurants that are near the park. I think these are more fun, and better food typically. Much like your selection of Chef Mickey's.
As for other Must Do dining, I do love Hoop Dee Doo Review, as well as some signature dining at California Grill. But you will know if your kid are up for that.
Finally, with regard to water parks, I would consider that something you do in the afternoon of one of your park days, in particular your days at Epcot and the Animal Kingdom.
Have a magical vacation!
