I agree. We went to DHS on a rainy day in early December of '08. It was cold and pouring, but we managed to make it through the rain and be there. We rode RRC with only a 5 minute wait! We pretty much walked on. And TSM had 45 minutes about but it seemed shorter than that.
We went another time around the first week in November (before thanksgiving). The crowds were alright except for on Columbus day weekend. Epcot (the park we went to) was packed.
