I am off to Cancun in 2 months. Never been there, so I wanted to "check things out" in advance. I bought this and Frommers Guide. I was not impressed by either one. Fodor's was especially short on info in my opinion. The Cancun section was rather small overall. I have found better information just surfing the internet. They give you some very basic descriptions and price guides, but no recommendations. I have never been there... that is what I need! Which tour is best, which ruins should I see, etc, etc. I got NONE of that! Frommers was a little better in that they gave you more diverse information, but no real recommendations. I will see if I can find something better than both of these before my trip. If you must choose between these two popular travel guides, go with Frommers.
