I'm not 100% sure, but I think you'll be there during the marathon (I think it's the 9th). So you may encounter larger crowds that weekend, but after they leave, you should be walking on to most rides. We were there last Jan. and it was a bit chilly (for Florida, it was quite toasty compared to our weather here in NE Ohio) and a bit rainy, but when you balance that with practically empty parks, you'll be glad you chose January. Have fun!!! --H
