I can't go on "repositioning cruises", which usually take place in April and October. On such cruises, the cruise lines move ships to more "weather appropriate" locations--in April they move some ships north, and in October they move them back south (at least, that's the way it goes here in the Northern Hemisphere!). The bummer is that as a teacher I can never go on such cruises, which are very often offered at extreme bargains.
How I would love to go on this trip!
