reliable
I used this guidebook on my recent trip to Arizona. It was accurate and a handy guide to have. It did not, however blaze any trails. What I mean by this is that the author does not uncover many gems, but gives precise information about what is fairly well known. Also, like many guidebooks, does not want to give thumbs down to any tourist attraction. For example, we went out of our way leaving the grand canyon to visit the Cameron Trading Post, which is a quaint sounding name for an overpriced store of Native American handiwork. The author did say that the Trading Post sold some fine and expensive products, but did not say that it is an overpriced tourist trap. Had he wrote this, it would saved us wasted hours.
However I gave the book 5 stars because it did help alot on our trip.

Invaluable Travel Guide!
We used this travel guide on our recent trip to Arizona. We had never been to Arizona before,so we used the rating system to help us chose what not to miss. We are so glad we took the time to use it to research ahead of time. We had a great trip with the help of Frommer's Arizona 2008!

WORTH THE PRICE
This was an excellent guide for people who have never been to Arizona. You can't get lost with it. The way it's organized makes it easy to read. You can go directly to the section you need without wasting time flipping the pages.
