OK here goes. I have never been to WDW over Easter, but we go over christmas all the time. They say X mas is the most packed time of the year.
We are DVC members and now know what to see and when.
I don't find it all that bad, we use EE and pick and choose what to do. If I don't see if this year , we will catch up next year. The parks have long hours and if you avoid mid day on the "HOT " rides you should be OK.
A few keys:
Make PS for dinner
Start early in the day
Understand that you will not see everything
Slow down and enjoy all the extra holiday stuff
Avoid MK of 12/25 & 12/31
We are back this year 12/28-1/2
