It looks like the only time we can visit US/IOA is March 27-31. Is that Florida's Spring Break? We'll have FOTL, but will the parks be unbearable? Thanks for any info you can give me.
Florida schools do not all have the same spring break. Each district sets their own spring break. Orlando public schools have Spring break March 14-17. Anyway, Florida school breaks don't have much of an impact on park attendance as most guests are from out of state.
With front of the line, you will be fine whenever you go.
