I went in September of 2010 by myself. If you can request a double bunk, they will honor it if they have space. I went by myself had a great time. The food was good and we had a great crew. It’s camping at sea but when you make friends with people, who doesn’t enjoy camping. Be prepared for lots of diving. I don’t know the last time I had such a great vacation. No cell phones, no e-mail. I can tell you more, but I’ll do it again next year with my wife. We’re going to make sure that we get two bunks. I don’t think you get a price break sleeping together and if you do the space would be good anyway. I went in between the hurricanes so it was a little rough but not bad.
I’d recommend it to all my friends.
