I've watched HEA from the Hub area close to ten times or so. When arriving for the After Hours event, my friend and I watched from Main Street. The difference was enormous for me. When you're in the Hub, it's dark all around you and the projections/fireworks/music take over all your senses. Even the people around me start to disappear. From Main Street, the lights of the shops were terribly distracting and lessened the experience for me. Luckily, I'm usually solo and can find a spot in the Hub without having to wait too long. Thirty minutes early max. Sometimes just ten.
I loved Wishes, and the song will always hold a special place in my heart. But I love HEA as well. The lyrics really get to me - about following your dreams and finding your Happily Ever After, which doesn't mean romantic love, necessarily. I think it's wonderful, and my love of the animated classics helps for sure. Maybe it's not for everyone, but I'll watch it as many times per trip as possible and cry every time.
Also, Tink at the end instead of the beginning is freaking brilliant.
