I cant decide whether to go in June or Sept. We have always gone in Sept and stayed on site and this year we were not gonna go, but I got the free superbowl ticket and then won 2 more and just got a confirmation phone call from Universal that the tickets are real. Anyway, How are crowds in June? Weather, how hot is it? When we go in Sept its hot but not too bad. We have a 4yr old and 10. Thanks!
