I'd wait......
We did Easter last year & the parks were packed..... there were loooooong lines for everything....at times with a 2 yr old that was potty training I wish they had a FP for the bathrooms!!!!
When you add in spring break with the holiday it's a recipe for crazy mad busy!!
By Thursday (following Easter) the parks had slowed down & were quite enjoyable but Sunday thru Weds were overwhelming.
