Wes - as Hondo says - contact the singlescruise folks - they may have someone who is looking for roomie and can't go without or maybe there is someone who is going solo and would want to lower their costs by sharing their cabin. Also, talking with them, maybe someone who booked may have backed out and cabin may still be available - I'd make your call quickly to them. Just looked at the site and they still have cruise listed. http://singlescruise.com/
See if you can get a 1a cabin - that is is the cheapest.
Let us know what you find out.
