I passed the calm suggestion along. They went up last year to check out the campus and didn't have any problems. This is just a mom who is a little nervous thinking ahead. (Probably doesn't help in a way that I can't go this time but on the other hand, probably better for me in the long run).
Yes, everyone has their passports and I have one as well so that I can go sometime, too. I'd love to see the area, have heard that it's pretty.
