We are going to Orlando in June, and I've already purchased park to park universal tickets. I am planning to go the US on Monday and IOA on Tuesday. If I wait until late evening on Monday and go over to IOA, is it possible I could knock out the Harry Potter stuff with thinned out crowds? I'm thinking if I could do that, I could then plan to do the other IOA stuff on Tuesday at Rope Drop and not have to compete with the early morning rush. I've read that WWOHP often thins out in the evening, but should I expect that to hold true in late June? Any advice would be much appreciated.
