hi there, I too am a first time cruiser, and havent decided yet whether the idea of a cabin share is what I want. There are some really useful hints and tips on the forum for cabin sharing. I am looking to cruise the Carribean in January, and I know cruisemates are organising a group cruise on Carnival Freedom 19th Jan from Miami, sounds like it could be a lot of fun, and since I wil be celebrating my 40th birthday on the 21st, I am seriously considering this cruise.
Just a thought, if you dont manage to find a cabinmate, and decide to book your own cabin, at least you could get to know a few people on the forums before travelling.
But I am plunging into the unknown as a solo traveller, so I dont have much advice to give Im afraid.
