Very informational and useful. While rather out of date, 2007, most of the information still seems to apply. The first section of the book is general cruise information; what cabin to choose, where to go, what to pack. The middle section discusses the different cruise lines and ships, their strengths and weaknesses, programs, how many pools, ect. The last section, which was the most useful to me, is about ports of call in the Caribbean, Alaska, Hawaii, and the continental US. It lists some of the sites in each port, restaurants, shopping, and the best, how accessible is the port. Some ports are in warehouse districts with a mile or two walk to any sort of site and some are close to town or even better, the beach. It was very helpful to be able to know whether I should book an excursion with the ship or if my family would be able to walk to somewhere.
