Thank you for the questions, the truth is we do not focus on port information so much in our articles, but we do cover some of the more popular ports.
The problem is that there are so many ports, and a lot of this is covered in the message boards.
We also now have sister sites such as wikitravel.org (Won the Webby for best travel site in 2007) and World66.com have a lot of destination information.
As far as knowing when to book a cruise, or how to get the best price, we have quite few articles in our "consumers affairs" area where discuss how to get the best deal on a cruise. Some of therse article I personally believe should be read by anyone who ever goes on a cruise. They are recent articles written by myself and Kuki.
