I had luck finding a good cabin mate on here before.
As of right now I have a Promenade Suite on the Freedom of the Seas all to myself (which is okay too). But I don't mind defraying my costs and helping out another solo looking to save money. I believe final cost was $1349, and I made final payment on Friday, so you would have to reimburse me. I can give you links to my facebook page to get an idea of what I'm like, and my travel agent.
The cruise leaves the 8th of November and returns the 15th. Eastern Caribbean with stops at Coco Cay, St. Thomas and St. Maarten (3 full sea days). Note - it's Sunday to Sunday.
I am 42, non-smoker, somewhat of a drinker, but not going to get bombed especially since I might do the Scuba cert and need to be in the pool at 8:00 am. I don't need someone to hang with since I am cruising with friends from previous cruises and will eat dinner with them. But if you would like to meet them and join us for anything - no problem.
I would prefer a female passenger who doesn't snore too loudly.
