People love using statistics to make their case, and at Cruise Shipping Miami, the annual cruise expo, things are no different. Tourism commissioners, cruise line executives and industry suppliers use facts and figures to support whatever claims they may be making about their ports, ships or products. Here is a selection of our favorite figures from the conference.

Over 18 million. Number of times Carnival Cruise Lines' Towel Animal Theatre has been viewed online, according to President and CEO Gerry Cahill (watch "Swans" here).

1,017. The number of butlers that will be aboard luxury line Silversea Cruises' ships in roughly a year. The line will soon offer butler service in all staterooms.

100. The square footage of the "Studio," a new cabin category that will be introduced on Norwegian Epic, NCL's hotly anticipated new-build due out in 2010.

229,630. Cost per berth to build Royal Caribbean's Oasis of the Seas.

1.24 billion. Cost of Oasis of the Seas (5,400 lower berths x $229,630).

29 billion. The dollar amount generated in Europe by cruise tourism in 2007, up 22 percent from 2006 (according to the European Cruise Council, an industry organization).

16. The number of cruise ship orders placed in 2007.

Three. The number of new cruise ships that were officially ordered in 2008.

Zero. The number of new cruise ships that have been officially ordered since early 2008 (there are three pending orders, the last one made by MSC in August 2008, that have yet to be confirmed).

Six. The number of top cruise line executives on the State of the Industry panel -- from MSC Cruises, NCL, Celebrity Cruises, Royal Caribbean, Holland America and Carnival -- who exuded optimism, even in these uncertain economic times.
