Hi Kari,
Your 7 year-old is the perfect age for
Mickey's Backyard BBQ. In fact, my family joined a group of Moms Panelists and their children at the BBQ last fall. Two of my kids were 6 & 8 and they had a blast! Your baby would enjoy visiting with the characters as well. Granted, you'll probably need to hold him or her while you dance with the characters, but it'll be fun!
I'm not sure if you have boys, girls or one of each...but I'd also recommend
Chef Mickey's. You'll visit with the "Fab 5" : Mickey, Minnie, Goofy, Donald and Pluto. This restaurant is great for everyone! Another fun meal is
Donald's Safari Breakfast at the Tusker House. You'll see Donald, Daisy, Goofy and Mickey in their safari gear. If you have daughter's you may want to book a Princess meal as well.
Hope this helps and have a wonderful vacation. Please let us know if we can help you further,
Kaylene
