Book excerpt: Completely updated every year (unlike most of the competition), Frommer's Cancún, Cozumel & the Yucatán features gorgeous color photos of the stunning beaches, the colorful underwater world, and the mysterious Maya ruins that await you. This authoritative guide captures all the glitter of Cancún, as well as the more rustic and authentic charms of Cozumel, which boasts world-class diving and snorkeling in the turquoise waters of the Caribbean. The authors have lived in and written about Mexico for years, so they're able to provide candid reviews of all the beach resorts, the best local dining, and the latest, hottest nightlife. Beyond the major resort areas, we'll show you sleepy beachfront towns, sea turtle preserves, and fascinating inland towns where you can bargain in local markets. You'll travel Mexico like a pro with our candid advice and handy Spanish-language glossary. Also included are accurate regional and town maps (including site plans of the major ruins), up-to-date advice on finding the best package deals, a free color fold-out map, and an online directory that makes trip-planning a snap! Other helpful guides for your trip include Frommer's Mexico and Frommer's Portable Cancún.
