Hi Betsy!
Thanks for your question and for visiting the Disney Parks Moms Panel!
Assuming that you can get an
Advance Dining Reservation (ADR) at one of the locations I'm about to list here, you will certainly take in a nice view of the fireworks over
Magic Kingdom.
California Grill atop
Disney's Contemporary Resort is easily THE best location to both dine and get an amazing view of the fireworks, either from your table (they dim the lights and pipe in the music) or, even better, from the outside observation deck. This is my top recommendation!
Next,
Narcoossee's at
Disney's Grand Floridian Resort & Spa offers dining right on the Seven Seas Lagoon. You can step right out onto the boat dock to get a great view of the fireworks. This would be my #2 recommendation.
Finally,
'Ohana at
Disney's Polynesian Village Resort offers a wonderful view of the fireworks directly across the Seven Seas Lagoon from Magic Kingdom. HOWEVER, this will depend on where you are seated.
Ironically, these three restaurants also happen to be some of the hardest reservations to get, but any of the three will provide a wonderful evening if you are able to get one of them.
I hope this helps and I wish you a Magical trip!!
Chris
