Good question, I'm not exactly sure how they are enforcing the times. We had tickets for 11 AM yesterday and we got there at 10:30 AM and we were not asked about time we were scheduled to go in. They let us just go in when we arrived. So, I'm assuming that they are not enforcing the scheduled times.
I purchased 12pm tickets and was there at 12:50pm. I am almost certain I saw that you need to be there within the hour though it didn't seem they checked the time anyway
