I'm no expert, but there are a LOT of schools in my area (NJ/NY) that are off for Spring break this week (my district was last week) so that could mean higher crowds for the remainder of this week as well.
I'm here now. It's the busiest I've ever seen it and I have done Easter and other busy times before (everything but Christmas week).
Today is a recommended day for MK - there were 100+ minute waits for many rides by 10:30 this morning. I still did tons of stuff without waiting more than 15 minutes .... By doing RD and using FP...
