I always forget to pack an empty beach bag for carrying lotions, towels, etc when lounging up on deck. As a result I always end up visiting the gift shop and getting another one - now I have a closet full.
Also, the last time I sailed I forgot to inquire about international cell service and ended up paying big bucks (when I could get service).
Happy Cruising!!!!! I'm cruising in Oct 08 on the Crown Princess....woooohoooo.
