Most of the cruise lines have stopped doing this because of so many complaints . I'd suggest you check the "Roll Call" board and the "Seeking Cruise Companion" board to see if there's anyone else looking for a roommate.
Good luck, and have a wonderful cruise!

Fern is right; Carnival still does this sometimes but that is about it. YOu do need to go to the special section, also post here and try CruiseCritic if you haven't already. Hopefully you will find someone that you can relate to. Good luck and yes, welcome to our board...NMNita
