Very basic, some history, a broad range of information about cruising. Overall guides to the ports, but not very specific with ratings or recommendations. If you are brand new to cruising, may be helpful, but for someone looking for Alaska travel guide, go with a specific travel guide and read the chapters you need. Overall, this wasn't what I was hoping for. Used it in addition to many other resources, and in total, this is the one I thought was the least helpful. 2.5 stars.
