Howdy Kristen!! Disney's BoardWalk Villas are great and you will enjoy the lively and fun atmosphere of Disney's Boardwalk. You have made some fantastic dining selections!
I would also add
Beaches & Cream Soda Shop at Disney's Beach Club Resort or
The Fountain at Walt Disney World Dolphin Hotel. Both offer yummy ice cream as well as lunch and dinner entrees. Beaches and Cream is very popular so you may have to wait for a table. We have always walked right into The Fountain. Both are loved and enjoyed by my kiddos!
While I realize you are most likely seeking table service suggestions, when staying at Boardwalk Villas, I try to immerse myself in the atmosphere of Disney's BoardWalk. You will find some amazing options at Boardwalk Bakery, the Pizza Window or Seashore Sweets. Grab breakfast, lunch or dinner and enjoy the Boardwalk. There are a few benches where you can sit and enjoy your meal or you can stroll along the BoardWalk as you enjoy a slice of pizza or snack.
You are also a short walk away from Epcot if you decide you want to head over to the World Showcase and enjoy any number of great kid-friendly locations.
I'm so excited for you!! I'm also hungry! Be sure to pick up some fried ice cream! You can currently find it at the Funnel Cake Cart near the entrance to the boat dock. Yummy!!!!
Thanks so much for your question and please let me know if you need any further information as you plan your vacation. Have a magical day!!
