Sherry,
The BoardWalk is a very short 10-15 minute walk away from the International Gateway of the Epcot World Showcase. You can also take the boat launch.
I think that your idea of going to the BoardWalk for dinner, then returning for fireworks is a great idea. But don't just look at the BoardWalk restaurants. There are some great restaurants in the Dolphin, Swan, Yacht Club, and Beach Club resorts. People often (understandably) overlook them, but they can be a fun and satisfying experience.
Some of my favorites, whether they are at the BoardWalk, Yacht, Beach, Swan, or Dolphin, include;
- Flying Fish Cafe (seafood)
- Il Mulino (Italian)
- Todd English's bluezoo (trendy cuisine)
- Kimono's (sushi)
- Cape May Cafe (buffet)
- Shula's (steakhouse)
And of course if you have a park hopper, you might even boat all the way over to Hollywood Studios!
If I can help with more precise suggestions, just let me know your dining preferences by sending me a question directly from my bio page!
Have a magical (and delicious) vacation!
