We were there June 3rd and 4th of this year - the weekend following Memorial Day. We stayed on site at the HRH, and honestly, with the exception of a few rides, we did not need FOTL access. The parks just weren't that crowded. We went to both parks on both days. We ended up at HP about an 1 1/2 hour before closing on Friday night, and TFJ was a walk on. The four kids with me did the Ollivander's wand show with only about a 10 minute wait that night. We went for early access the next morning, and everything was much more crowded - the wait for Ollivander's was at least an hour or more, and as we were leaving Hogwart's, the standby line was outside of the castle, going over the bridge.
We have decided that if we go the same week next year, staying onsite just isn't a must do for us anymore. We are DVC, and used to staying in larger villas, and it was hard for the 4 of us to stay in one room at the HRH.
