I feel like such a dumb-dumb. my young non-school age family is going March 4- 10th. I've been crazy obsessively planning this trip since our last trip, but somehow I missed it on cheking the crowd levels by number. The 8th, 9th, and 10th are all at level 8 out of ten. I'm freaking out because we thought we were going before the spring break crowds begin... 
It's silly for my non-school aged family to go when everyone else is going but I'm worried about the cost of changing flights etc.
How bad are the parks at level 8? Is it worth the hassle and expense of changing the dates to a week earlier?
