This is just a suggestion to all you who are looking to cruise but don't have a travel buddy. Why not check out an organized singles cruise?
Read Ann Cambells Singles cruise calender on this site and take your pick. Some of the agencys are Vacations to Go,(click escorted singles cruise) Cruising for Love, and Singlescruise.com. You don't have to be going for a romantic hookup you can just go to make friends and have a good time. You will not be lonely or stuck with one person you might not be compatable with because you will have a large group of people to hang out with and private group activitys. The agencys will find you a same sex roomate or you can pay extra for your own cabin.
Also read the singles forum for information. Last year I booked my first singles cruise, had such a good time I booked another one months later. Im now going on my 3rd. It's not a drunken frat party atmosphere it's a bunch of good people who happen to be traveling solo.
