I have to agree with Gschmerl here. We were also there last year (first week in August) when they had it in place. Before we went, I was livid that they had changed the rules. However, once we got there, we found it to not be an issue at all.
Early in the morning, you didn't even need to use FOTL, so we would ride Hulk, Spiderman, etc numerous times till the parks started getting busy. That left only about 4 1/2 - 5 hours where they were supposedly limiting it. At times they did, but there were also times they did not enforce it.
So, after riding everything we wanted in the mornings, we would then ride everything once again with the 1 time FOTL. Low and behold, it was then at least 3:00. Now we had a full 7 hours (parks closed at 10pm when we were there) to enjoy unlimited rides.
In the beginning, we thought we were being smart and even pulled express passes for the limited rides to pad our 1 time FOTL. We found that we never once had to use the Express passes. Either it was past 3:00 by the time we returned to ride or they weren't enforcing the limits. We ended giving LOTS of express passes away or just not using them. In fact, I have several Hulk express passes in our scrap book that we never needed to use. After a couple of days, we just stopped pulling Express passes because we realized we were just taking them away from people who could actually use them.
So, for the 4 1/2 hours where the heat is unbearable and the crowds thick, I can live with the 1 time FOTL. If they enforce it this year during our July trip, I won't care. Just give me the 7 hours after 3pm of unlimited rides!
