There aren’t really any tips… it’s hurry up and wait all day. As far as LASIK I didn’t have anything extra while I was there(I had lasik as well). I would still change your flight though because our last day we didn’t get out of the building until like 1530 I think and that was due to the testing on the computer. Just go in there have fun make some new friends and don’t worry about it. Nothing you can do to prevent anything that may come up while you are there.
