Hi Archana,
The answer depends on which fireworks you are trying to view. If you are trying to see part of
Illuminations:Reflections of Earth at Epcot, you can see most of the higher fireworks on the walkway from Disney's Boardwalk to Epcot's International Gateway.
If you are trying to watch
Wishes nighttime spectacular at Magic Kingdom Park, you have more options. There are several restaurants that offer a great view of Wishes. They are more than likely booked at this point, but I have occasionally found last minute openings.
'Ohana at Disney's Polynesian Village Resort,
California Grill at Disney's Contemporary Resort, and
Narcoossee's at Disney's Grand Floridian Resort all offer a spectacular view of Wishes.
In the past I would have recommended viewing Wishes from the beach at Disney's Polynesian Village Resort but there is a significant amount of construction happening at that resort. With the crowds of New Year's Eve, they might not let extra guests on the limited beach. My next choice would be to pick up a dessert at
Gasparilla Island Grill at Disney's Grand Floridian Resort. There is outdoor seating with a lovely view of the fireworks across the lake.
Thanks for stopping by the Disney Parks Moms Panel!
Wishing you a magical vacation,
Amy H
