Yeah, those are all guesses and estimates to get an idea on the number of slots available. Lots of room for error, but it gives an idea. I think I read that they lowered the default max number of people per membership and that they are restricting registration to one of the two days offered (that they didn't restrict for the same event in the past is surprising, though not shocking). That might be helping quite a bit for the registration rate too. I think it is great that they are offering enough capacity for those with reservations to sign up without getting shut out. We will see how busy it is on the 5th. Wow, my vacation is coming up soon!
