The size of the VIP seating was greatly reduced when we got there on Sunday morning, then more chairs were brought out later for Large Coed? The back row of chairs in VIP backed up directly against the parent section and as much as I knew those chairs in the center back row of VIP were probably the best seats in the building, i couldn't bring myself to sit there knowing I'd be blocking someone's view with my back. It would be nice if they could raise the VIP seating up on some staging and then put the parent standing section in front of that. Most of the people in VIP really do want to watch the competition, and like you said, they've shelled out tens of thousands of dollars to send other peoples' kids to Worlds. Putting the parents in chairs in front of other chairs on the floor would be hard because I'm sure it's hard for those parents to stay seated while watching their children compete at Worlds.
Most of the people in VIP were coaches, EPs made up the second biggest part. As far as I could tell, that section was not empty at all at the times the rest of the milkhouse was packed... Other times, yes... but there were lots of other chairs open around the venue. I witnessed many of the EPs cheering on teams, standing up to clap after performances, not wasting that space. I'm sure most people that were in there have made careers in the cheer industry because they love the sport, too.
