Okay, putting aside that SAN is a prepubscent and therefor get's a bit of a pass on her (his?) niavity...I say, ladies....go have a great time and have a little ship board romance if you want (but bring condoms for pete's sake and be responsible). I did it about 15 years ago (with a Cuban Dive Instructor...oh my, my heart still beats!!) and we corresponded for about 6 months...no harm, no foul.
Another thing...I don't think that Immigration grants green cards based on marriage anymore....
So, SAN, here is my advice...go back to Camp Carnival and let the adults take care of themselves..
