We were there for Spring Break last year. I live in Georgia. The early days were pretty good. We had normal wait times. Oh my goodness... those later days? We would literally RUN to our favorites at IOA because they literally had 180 minutes wait times on the Hulk and Spiderman.
OK, think about it... 180 Minute wait times! 3-hour wait times! During the later part of the day, if a ride had 60 minute wait times, we were in the line.
But all in all, we had a great time... so much in fact, that we went back that next month and had a blast!
But if you were to avoid or reduce wait times, you can book an onsite hotel. That will reduce it by a great deal.
