The crowds vary wildly at Disney World. First time I went with my kids we did the first week of November. Not many people at all, and we could get on a lot of rides without much of a wait and it wasn't too crowded. Bonus: We got to see the Halloween decorations the first day we were there, and then Christmas decorations for the rest of the time. 10/10, would go again.

The second time we decided to do a Christmas trip. There were two days where Magic Kingdom literally told people there wasn't enough room. Even Epcot and Hollywood Studios were crowded, and we didn't get on many rides. The hotels were loud, too. 1/10 would not recommend.

However, I haven't bothered looking at prices because my kids are grown and I'm happy being at home, but if I had to pay 50% more for the first experience it would have been worth it, and the second I wouldn't have taken even if it was free.
