I saw World of Color for the first time this past March and I will say that it is a pretty amazing show. I don't think it beat out Fantasmic (personal preference) but it was cool. At least what I could see of it. I did the FastPass to get the viewing area, I think I was in Blue, and the main thing I noticed right off the bat was all the people with giant strollers parked near the front and all the tall people standing in front of me. I'm only 5'5" so having anyone taller than at least 5'8" in front of me really sucks.
While I was sitting and waiting for it to get dark I couldn't help but think how they could have set things up better for the viewing areas. They had all that time to remodel Paradise Pier and could have put in some sort of stadium set-up or stairs so that shorter people, and children, would have an easier time watching the show. I wound up watching most of WOC through my camera LED screen because I could barely see anything and by the end of the show my arm hurt from holding my camera up for a half hour. Most of what I could see with the naked eye was the tops of the high water spouts. I have watched a couple decent YouTube videos of WOC to fill in the gaps.
Definitely the least planned out viewing area, imo. It's not like the fireworks displays where it doesn't matter how tall the people around you are. Anyone agree or have a similar issue?
