We've been down there twice after Pres day. It was great. The second time we went, Boston had a major snow storm and we had to extend our trip by 2 days! We were lucky, we had DVC so it didn't cost us any more money (only points) for a hotel and we had bought the annual passes so had more time in the parks!
I don't think it will happen on this next trip, we are going in May.
