Galveston, Texas offers everything from entertainment to shopping, to over 32 miles of Gulf Coast beaches. Galveston's festivals, special events and attractions are enjoyable for islanders and tourists alike. Arts and entertainment is as much a part of the area's history as its Victorian architecture, and Galveston sparkles at night, from theater, music and dance, to reggae, rock and country.

Sitting just off the gorgeous Yucatan coast, Cozumel revels in its mythic white-sand beaches and world-class coral reefs. Yet Cozumel is also the last stronghold of the Mayas, who settled the island in 300 A.D. Residents still speak Maya, and sometimes wear traditional Mayan clothing. Nearby stand the great pyramids and temples of their ancestors.
