We just got back this evening, having been to the parks all week. I thought the parks were all quite crowded compared to when we went in September. However, the crowds did not really affect ride wait times for the most part. It seemed most of the lines were just about the same, from practically walking on Space Mountain to a 20 minute Jungle Cruise stand-by. So the crowds made maneuvering our stroller more difficult, but we still rode everything we wanted to without much of a wait.
