I have watched from Poly and from in front of the castle, not from Fantasyland yet. My strong opinion is - just like Wishes - there is a place for ALL types of viewing locations. They are all going to have their pros/cons, but like a PP said it's still a great fireworks show at the end of the day. Yes, you should definitely try to see it from the "front" because that is now a more dramatic viewing area. But as time goes on, you've seen the show before, etc, these "no projection view" spots like Poly, like CR, like Fantasyland, are going to be just as valid, in my humble opinion. We'd migrate our viewing around to different spots for Wishes, I don't see that changing for us with HEA. Frankly I can't wait to watch it from Fantasyland - it's always been so loud and right on top of you from back there.
