This book is an amazing compilation of ways to save money by traveling. For example, if you go to Disney World and are "sponsored" by a legal resident of Florida you can get savings of up to $100/person on ticket packages. The resident must come with you to the ticket office to do this. There were all kinds of tips that could even be applied to business travel in some cases. This book is a must for anyone about to spend significant dollars on travel virtually anywhere.
