Danielle,
If you want to get some breakfasts into your schedule, here are the ones I recommend based on your park days;
Magic Kingdom (2 days)
Chef Mickey's
1900 Park Fare
Animal Kingdom
Tusker House
Hollywood Studios
Boma
Epcot
Akershus
Now assuming you don't want to do all these, the order of preference for me (characters aside) would be: Tusker House, Boma, Chef Mickey's, 1900 Park Fare, then Akershus. You might also notice that I did not include Crystal Palace within the Magic Kingdom. While the food can be fine, unless your kids are into Winnie the Pooh, or you really want to get in the park before opening time for some pictures, then I think the other choices are better.
Specific to your other questions, I prefer Tusker House to Akershus, though some of the appeal for either is their respective, and different, characters. Between the Hoop Dee Doo Review and the Spirit of Aloha Dinner Show, I far prefer Hoop Dee Doo. Your kids will too.
Keep those questions coming! These are fun!
Have a magical (and delicious) vacation!
