Hey there, Alycia!
Welcome to the Disney Parks Moms Panel!
Wishes Nighttime Spectacular is the icing on the cake for ending a Disney day!
The best way to get to Disney's Polynesian Village Resort from Disney's Art of Animation Resort is to take a bus from your resort to the Magic Kingdom. From the Magic Kingdom, you can either ride the Monorail or take a ferry boat. I would suggest to take the ferry boat. It's a little quicker than riding the Monorail.
If you take the Monorail, it will drop you off upstairs in the main building of the Polynesian. So walk downstairs and head to the beach area to enjoy the view.
If you decide to take the ferry, it drops guests off near the beach area! You won't have to go far to find a spot!
While at Disney's Polynesian Resort, stop and enjoy a sweet treat at
Pineapple Lanai! Dole Whip makes watching fireworks even more magical!
Wishing you magic and memories!
