I would personally say get in at 11am then and then you can decide to definitely leave an hour early still if you wish. I worry if you go in 30 minutes late you may then realise how much you want to do and not leave early. Especially if you want to do shopping first. As the reservations overlapped we could do empty spaceport shopping at like 8:15 but when we went back to get one more shirt at 11:15 when the second reservation period had been let in, it was getting a bit manic. And the Falcon went straight up to like 80 minutes then. When it had been a walk on only a short while before. The milk queue (not something I thought I would ever type

) was getting long too then and the PhotoPass queues in front of the Falcon particularly must have been over 30 mins then.
