Hi Casey,
The dinner shows are so much fun! They are two Table Service Meals if you are using the Disney Dining Plan. My favorite show is the
Hoop-Dee-Do Musical Revue. This is fun for kids and adults of all ages! My kids were ages 5,8, and 12. Everyone laughed until they were crying and the food was great. The corn bread and fried chicken and BBQ ribs were fantastic! We were on the first floor near the back, but I think being up in the balcony would be a good location as well. My kids still bring this up (two years later) and can't wait to go again!
The Campfire Sing-Along with Chip & Dale at the Fort Wilderness Campground is a hidden gem at Walt Disney World. This is a free event and no reservations are necessary. You can purchase marshmallows and chocolate and sticks to make your own s'mores. The sing-along usually lasts around 40 minutes. Chip and Dale will make an appearance and will sign autographs and have their photos taken. After this, a Disney movie will be shown on a large outdoor screen. I think all of your kids will have a great time!
At Animal Kingdom, a wonderful show that is a must see is "Finding Nemo- The Musical." This is in Dinoland U.S.A. and all your kids will love it. It is a live show with life- sized puppets. I have so much more to say about this subject, Casey, but have run out of room. Please send me a follow up question if I can help you further. I hope you have a magical vacation.
