Query: If you are clueless, start with this book

If you have absolutely no idea what you want to see, or where you want to go, then this book could help you. However, if you shop on Amazon.com, you can get the same information this book provides at any of the cruise websites.The information in this book is basic and cursory, and it provides no real helpful tips. I was looking for hints on what shore excursions to pick, where to eat in port, etc. I didn't find anything remotely helpful. I haven't read the other cruise guides, but certainly would NOT recommend this one unless you are starting to plan a trip and know absolutely nothing and don't like to read online.
