Query: Frommer Has a Winner Here

I hate most of the Frommer Travel books. They take the fun out of travel and have very few photos.This book is different. Here they came up with something very useful and novel for the traveller. When you go on a cruise normally you do not have a clue. You just follow what your travel agent recommmends. But anyone that has taken an extended cruise or two knows there are big differences betweeen boat lines and routes etc.( I like Holland America myself). So here is a nice review of what boats and crusies are available, it describes the boats, and where they go and what you can expect including on board entertainment. All great stuff.Highly recommend 4 or 5 stars. Buy before you talk to the travel agent.
