Many cruise ships require a shift to a new location when seasons
change. For example, a cruise ship in Mexico in the winter will go
to Alaska in the summer. The cruise that moves the ship to its new
location is called a "repositioning cruise", and they typically are
very good values from a cost perspective.
One of my friends is a cruise director for Princess Cruises, and I
had an idea that we could all load our bikes on the cruise ship in
May's repositioning cruise from Mexico to Vancouver, take the cruise
to Vancouver, and then ride down from Vancouver on our bikes. The
cruise would begin in L.A., where we would load our bikes on the
ship and enjoy the week on the ship.
I am working on getting the details, and in the meantime if you are
interested in doing this, please let me know.
