You'll be there 7 days and 6 nights? So, you'll have 6 TS credits? Where will you be staying?
Let's see...
Arrival Day/Night (1st night) -
Chef Mickey's at the Contemporary - a dinner buffet w/ all the traditional characters (Mickey, Minnie, Donald, Goofy, Pluto) - a great way to start your trip!
MK Day (2nd night) -
Crystal Palace (breakfast, lunch, or dinner) in the MK - yummy buffet w/ the Pooh characters
OR
Whispering Canyon Cafe (dinner) at the Wilderness Lodge - I think your boys will get a kick out of the antics at this restaurant; it's a short (relaxing) boat ride away fromt the MK
Epcot Day (3rd night) -
Coral Reef (lunch or dinner) - unique setting w/ the aquarium
OR
World Showcase restaurant (lunch or dinner) - Le Cellier, San Angel Inn, Rose & Crown, Biergarten, etc.
Disney Studios Day (4th night) -
Sci-Fi Dine-In (lunch or dinner) - your boys will probably like eating in a "car" & watching the funny sci-fi movies
OR
Fantasmic Dinner Package at Mama Melrose's
AK Day (5th night) -
Breakfast w/ Donald & Friends at Tusker House (if you wanted another character meal)
OR
Boma (dinner) at the Animal Kingdom Lodge - great buffet w/ lots of options, and the resort is absolutely lovely - a perfect ending to a day at the Animal Kingdom
Extra Day (6th night) -
Ohana (dinner) at the Poly - great food (lots of it!) w/ a nice view of the MK for your last evening
Departure Day -
Maybe pay OOP for a yummy breakfast at some place like Boma at the Animal Kingdom Lodge or Kona Cafe (Poly) for your last day?
OR
Schedule Chef Mickey's for breakfast on your last morning (instead of your arrival night) or the character breakfast at Ohana.
We like the following counter-service locations in the parks:
MK - Casey's, Columbia Harbour House
Epcot - Sunshine Seasons & trying some of the WS counter services - if you don't schedule an ADR at one of the WS restaurants, you might consider trying one of the WS counter services
Disney Studios - Toy Story Pizza Planet
Animal Kingdom - Flame Tree BBQ
Downtown Disney - Earl of Sandwich
Happy planning!
