I cruised every birthday by my self for the last four years, They usually bring out a piece of cake with a candle in it then proceed to embarass (sp) me by singing Happy birthday. I usually get a present from someone Ive met on board that night. However it's not something I can ever see or use again ...lol
As for the costume for Halloween just ware your Birthday suit....It's your Day
Happy Birthday and Happy Cruzin
