I like reading cruise statistics and trends:

The global cruise industry generated revenues of 37.1 billion U.S. dollars in 2014, a figure which was expected to increase to approximately 39.6 billion by the end of 2016. The industry made significant recovery after revenue fell below 25 billion during the 2009 global recession. The number of passengers carried by the cruise industry has grown year-on-year and is expected to exceed 25 million in 2019. The average cruise passenger brought a revenue of 1,779 U.S. dollars, but, with expenses per passenger also high, the average profit was only 226 dollars in 2015.

Where do you see the industry heading?
