Go on the cruise. If you're really worried about not matching, it sounds like you'll be back in time for the scramble (2 days before Match Day) anyway. As Jane Dough said, you'll be happier sitting on the boat in the sun with your buddies than freaking out at home alone.
After interviewing, I got an opportunity to teach in eastern Europe, so I went, didn't match, and had to scramble, from Serbia and Montenegro. With modern telephones, internet and your trusty laptop that you've digitized your CV, transcripts and LORs/PS's into, as wells as the ERAS application data, I was able to scramble into an excellent residency in an outstanding location. In those days, the scramble didn't use ERAS like it does today. You had to fax/email your stuff.
Then, letter of intent in hand, I went skiing! Sarajevo was fun, no crowds, bright and warm sunny days.
I spent some money on the Internet Cafe, and phone cards, but, if you're in LA or Boston, in this day and age, with faxes/emails readily available, it's pretty easy. I did have one program comment on my overseas fax number, but I assured them I was a US national with a US medical degree, and that was enough. Enjoy your cruise.
