Explore the Eastern Caribbean for seven days, roundtrip from Miami and experience the picturesque island of St. Thomas. While the duty-free shopping is perhaps the best in the Caribbean, its striking blue water and beaches, like Magen’s Bay, are indescribably beautiful. Take the Skyride to Paradise Point for awe-inspiring views. Tortola is the largest of more than 50 British Virgin Islands and its velvety white sand is legendary.
