Since the Concordia crash, I've been doing some research on the cruise industry.

I've never been on a cruise, but if prices drop, maybe I will give it a try.

More than 11 million Americans went on a cruise last year.

More than 5 million Europeans went on a cruise last year.

The tipped over Costa Concordia is owned by the Carnival Corporation.

Carnival has 101 cruise ships sailing under the names Costa, Carnival, Cunard, Holland America, Princess and Seabourn.

40% of the cruise industry is in the Caribbean.

The cruise industry has a high rate of repeat customers.

More ships are being built because demand is going up each year.

Book early to get the best rates and room selections.

What else should I know about the cruise industry?
