I must comment about some of the statements here. First, Jan is a slow time, but so is Sept and October and there were no MAJOR rides closed like TT and Splash, and Buzz is a huge draw too. Also I really feel sorry for those people that will miss all three of those rides! We have been lots of times in January, and yes have hit things on refurb. but NEVER more than one thing at a time. What I do remember is that when Space Mtn was closed, big thunder and Splash were much more crowded. So with Buzz and Splash closed at the same time, I can only imagine what Space and Big thunder will be like. Also makes Soarin that much more crowded if TT closed.
And Presidents weekend is very busy! Lots of FL residents go then! It's noticeably more crowded in MK, and MGM, and AK when we were there!
What does worry me as well is that the UG shows Late Jan early Feb crowds ranging from 5-7. I think Jan has become a popular "off season" (AND again the UG book had Sept and Oct crowds at 4-5, and no biggies were closed...well except for hurricane closing)
