Disney Girlie-
We went at the same time. 1/30-2/03. I am a little phobic about crowds, so I make sure it is not near any holiday, check cheerleading and dance competition schedules, and even randomly check public school schedules all over the country, to make sure no one has a break. I also check touring plans.com. They list projected crowd levels by the day. Then I plan our park days pretty compulsively, again using touringplans.com (or unofficial guide book), to determine best day for which park. I certainly did see some crowds, but our touring plan kept us ahead of them. I saw lines, but didn't wait on them, and still did everything we wanted to do. I always go at low season, but Fantasyland is always mobbed in the afternoon-always. So, we always go right to fantasy land early on MK days, and have it to ourselves for the first hour. Also, it can just be luck. We went same time in "04, and crowds were slightly more.
