Once only the rich could cruise (on a ship)! Now with the average cost only (?!) $222 USD PPPD, it is a lot more affordable (Cruise Market Watch). And CruiseCompete.com can find you cruises under $300 USD!
And we find the bulk or cruisers from North America. That makes sense with the Caribbean so close. But the world is becoming a cruise destination as some geography research has found.
Not counting canoe trips in my college days, I have only been on one cruise and that was the inside passage from Whittier Alaska to Vancouver, Canada. A great time and one that I hope to revisit as a form of last chance tourism.
