We were at WDW from 12/30 -1/7 and we expected the crowd over NYE but everyone said it would slow down by 1/2..uhh NOPE it was just as busy if not busier. We have been to WDW every year since 2010 and different times during the year but every year it gets more crowded which I don’t quite understand because every year it gets more expensive. I don’t think you can go by school calendars or crowd calendars or anything anymore because it seems like there are large groups from all over the world there at different times,
