Hi Susan!
Thanks for your question and for visiting the Disney Parks Moms Panel!
I figured I'd grab your question since I'm a fellow Bostonian. Go Pats!!
As you know, February Break is coming up for schools in the Northeast, at least in Massachusetts. This will certainly affect crowd levels at
Walt Disney World Resort and in the
theme parks. The good news is that the weather will be awesome compared to back home, so you may even be able to get a day in at
Typhoon Lagoon or
Blizzard Beach for a day of sun and relaxing and recharging tired legs!
This is also the unofficial start to the Spring Break season which lasts through April, so I would expect higher crowd levels than earlier in the winter. I will say this, my girls and I have visited during Thanksgiving, February Break and even April Break and we have never found it to be THAT bad. Busy, yes, but still loads of memorable fun!
I hope this helps and I wish you a Magical trip!!
Chris
