I was there in October 2010 on Monday the 4th - Thursday the 6th. Crowds were very light. Since we were there for our DD 4th birthday we didn't go on a lot of the mega popular rides but for the things we did I don't think we waited more than 15 minutes for anything. Our longest wait might have been for Peter Pan, other things we almost walked on.
I am really hoping that this will be the case for us too! I WANT those light crowds!! LOVE the rare times when rides are all walk-ons! We are doing the Oct. 2nd party too, in fact, it's our last day! I can't wait!!!
I've personally found that the weather forecasts so far out are not very accurate. I started watching the 10-day forecast for our visit at the end of August. Things were looking good. Then it started to creep up a degree or two each day...and by the time our trip happened, the temperature was 12 degrees higher than when I started watching 10 days out!
We are just doing the party on the 2nd, then DCA on the 3rd & ending with DL on the 4th.
I was able to save a bit of money & buy the gay days tix since they are good starting on the 3rd. Sweet!
I'm a little concerned about crowds for the 4th since that's a day before the official start of gay days. But I'm just hoping if folks come in early, that they will head to DCA for Carlsand while I'm over in DL.
