there is that maasdam (holland america) cruise that leave ft laudersdale (and has a pretty good itinerary) and returns to ft lauderdale--but it's 42 days long, which isn't too much for me--but it may be for some people.
wish i knew how to better navigate the 'systems'. i'd like to take several consecutive trips. i'm stationed in so cali--so maybe panama canal to ft lauderdale--east-coast/canada--maybe some barbados/carribean action--then transatlantic and some mediteranian/n. europe, etc. then transatlantic and back to so cal without getting on a plane. seems like you get a lot more bang for the buck on a cruise than on a plane. save the asian/australia/so pacific for next time. i don't see myself running out of new places to go and see.
i wish there was a good central resource for discounted solo supplement cruises. seems like the same ones have been on vtg for several months. would also be good to have a regular travel amigo/amiga to take the sting out of solo cruising.
