Travel between Cancun & Antigua Guatemala.

Mexico
Mexico is the 3rd major country on the North-American continent and the only one where Spanish is the first language. Mexico-for-tourists is known for Maya ruins, beaches, excellent food, Mariachi music and great weather. Mexico city is one of the largest cities on the planet.

Cancun and Playa del Carmen are famous beach resorts on the Riviera Maya with the best hotels, bars and a lot of US-Americans.

Old Guatemala is a nice, colonial city amidst several active and inactive volcanos. Several tourists settled here and opened little shops and restaurants. Highly recommended.

If you like to learn Spanish, this is certainly one of the better options with a wide variety of schools. 4-6 hours per day for a month with overnight stay at a local family and you are ready to discover Latin America.
