Haha. Sorry about the boat comment. I thought that was kind of funny. Thanks for all the great advice. The ship will actually leave you if you are not back on time? What will you do then? Sounds kind of odd to be stranded while one vacation. It doesn't look like scuba will have such a big problem though since that excursion usually runs pretty short. I have scuba'ed before (the newbie stuff), but I just want to introduce it to my family. I am really afraid of booking with just some no body and ending up like the movie "open water." Maybe I am just being too paranoid....
