I'm seriously thinking of going on a 3 or 4 day cruise in March during Spring Break next year with DF....but the other time I cruised (with Carnival in June 2005....and loved it!), I went for 5 nights. I loved the cruise, but I only wish it could have been longer...I would really want to do a Disney this time...I really want to check out Castaway Cay!..but I don't know if I can afford a longer cruise....are the 3 or 4 day cruises worth it? Or should I spend more time saving (or try and see if I can have more money by March) for a longer cruise?
