Query: Best of the RTW travel guides. Period.

We're 7 months from an 11 month trip around the world and this book is IT for authoritative information. If you are flying to a vacation spot you need this book. Although the book is long and detailed we found it's completeness a real help. Hasbrouck is a detail oriented guy that you would want for a travel agent. His section on air travel is unbeatable. I have read nearly all of the round the world guides and this is the best bar none.
