I wasn't apart of the family of anyone that competed this year, I knew some athletes and had very good friends on teams, but I didn't come down to support a family member or vacation, I came to watch worlds. I agree that the issue isn't with too many bids being given out (that is a whole other issue all on its own) but I bet that a lot of people went down for the same reason I did. To watch worlds, whether they had friends, family, or someone they knew competing, they wanted to watch the best competition in the cheerleading world, and when people are paying $50 to watch the competition I'm sure they don't want to be sitting in a baseball stadium watching a screen. I certainly wouldn't have.
Its a fact that we have outgrown the milkhouse. I had to go at 6am to get a half decent seat and not leave it for the day. But the "come early" argument doesn't exactly hold up well either, because if everyone starts coming at 6am, we will just have the exact same issue, earlier in the day. I don't know where they need to move worlds to, and I don't know if there really is a location that would work as well as WDW used to, but I think its clear that the milkhouse is no longer big enough for our fan base.
