Well, I think that is what the OP is trying to determine.
What are the crowds like in Oct, so she can decide if on site is needed. I was originally considering late Aug and was going to spend a night at a US hotel. Now that we are going in Sept, it is harder to decide if I should spend what I consider a crazy amout of $$, just for one night, if it isn't going to be necessary.
My kids have been looking forward to going, but they have even mentioned postponing the trip until next year, but then I'll have 2 kids in high school, one in all honors program, so it gets a little dicey taking them out of school.
It would have been so nice if WWoHP had opend in early 2010!
