Definitely do not stand where a tree is blocking the LEFT side of the castle. Most of the fireworks are on the left side of the castle. Stand either on Main Street or slightly to the right. Or if you want a truly amazing view hop a monorail over to the Polynesian beach and then ride the monorail back for the rest of the party.
I saw Hallowishes from inside the park and from the Poly beach and liked the Poly beach way better.
Definitely Main Street if in the park. We watched from Liberty Square and thought we had a pretty good view. Then we saw the video posted on here and realized how much we actually didn't see. They still rocked, though.
My mom and a co-worker will be viewing it from California Grille on top of the Contemporary on Thursday. (They'll be at Whispering Canyon Cafe tonight, I told them to ask for ketchup! :lol: ). I'm so jealous of them!
