I am planning a 4 day trip to WDW. Should I go 4 days sometime prior to Christmas (which days?) or 4 days post Christmas (which days?)? When are Chrismas decorations removed in the parks? Thanks!
The period between Christmas and New Year is supposed to be the busiest time at WDW. I would suggest avoiding it and going before (as already mentioned)
In all honesty, you need to go the week before Christmas (the weekdays). They usually have longer hours and less crowds than Christmas Week. Plus, all of the great holiday decorations are up.
