A friend of mine went on a cruise last week and I was just curious to see how expensive they are. They are down right cheap! Once you've invested in getting a passport ($150, so not cheap) going on a cruise, departing out of the city down the road, is $35 a night! That's room, board, entertainment, child fun, cool! So it's not something we'll do for a while. But it's something I never imagined doing and suddenly it is quite high on the list of things I might do.
