Fifth Avenue in Playa del Carmen, Mexico. Once a sleepy little village on the Caribbean side of the Yucatan, Playa is now a thriving cruise ship port. The beaches, wide and blessed with deep, soft, white sand, are some of the most stunning in the world. As the town grew in popularity, restaurants and shops opened along Fifth Avenue, just one block off the Caribbean Sea. Today visitors can choose from traditional Mexican and Mayan cuisine to a variety of international cuisines, and many designer brands line the cobbled pavement of Fifth Avenue.
