Just a theory....on the Florida parks only. Disney was having difficulties filling hotel rooms from late August through early October. That supposedly was one of the major reasons to move the opening of GESWL up, in order to fill those empty rooms. But, even after the announcement for an end of August opening, the on site hotels still had tons of vacancies. The last four or five years, the weather cycle for the southeast has been brutal for traveling, driving/flying, from late August through early October. Tropical storm and hurricane disruptions throughout N. Carolina, S. Carolina, Georgia and Florida have made it a real hassle to schedule a vacation in Orlando for that time of the year. I used to always go in September/early October, but no more. After a few years of pure travel hassle, I quit scheduling a vacation in Orlando at this time of year. Perhaps that's becoming a bit of a growing tourist trend. After a few years of trying to work around the weather, tourists may becoming hesitant to travel to Orlando at this time of the year. Prior to this really bad cycle there was a fairly long safe weather cycle, and those were the years people started traveling to Orlando during even this slower season and had turned it into a season with many moderate crowds.....Fortunately for Universal, HHN is still a strong locals event, so that should keep those HHN nights busy.
