Hi Catherine!
Thank you for visiting the Moms Panel!
Yes, in the same way that you are welcome to visit the Walt Disney World Resort hotels for dinner, or a drink, or just to explore the beautiful resort surroundings, you can visit the beaches of Disney's Grand Floridian Resort or Disney's Polynesian Resort to view the Wishes fireworks.
You could also make a dining reservation at the Polynesian for that evening - at
Kona Cafe or
'Ohana - or at the Grand Floridian at one of the many
restaurants there - all dining reservations can be made
online, or by calling (407) 939 3463.
If you have any more questions, please come back and ask me - I would be happy to help you plan your magical vacation!
