I unfortunetely have to plan very far in advance (timeshare owner) and want to go in the fall of 2007 and was wondering the best time period to go. We can go the last two weeks of September - the end of October, with the exception of Columbus Day week. Which would be a better week where the parks are still open later (not as late as the summer, I know) and I can avoid crowds. I was thinking that the end of October gets busy because of the Halloween festivities? Is that true? Are the hours later because of that? Also when does Columbus week start to get busy and how long through the week does it last? Any help is appreciated!
