We were there in Jan. 2 years ago. We walked onto every ride with no (or very little) wait. My kids did all their favorite rides 3 or 4 times in a row - no wait. At Epcot, we got to the entrance at about the same time that the character bus showed up. There were so few guests there, we got hugs from all the characters - really a highlight of that trip. The only drawback is the shorter hours. Also, we did soooooo much, that by the end of our 3 day visit we could barely walk! This year we're going the week after Easter, which I'm sure will be a considerable change. Still expect to have fun - we just won't expect to do as much!
Have a great trip!
