Has there been more discussion about the language in the survey that was posted regarding having to receive a pass to come back to either side at a certain time? While I have no doubt the logistics have been thought out, I can't help but wonder if that means people would be kicked out after awhile. For example, if you make it to Diagon Alley via Hogwarts Express and are given a return time of 3:30, what if Diagon Alley is packed at 3:30? Are you denied entrance? Will people who have been there for awhile be asked to leave?
