13 Night Spain & Morocco Transatlantic

One of the largest islands in the Eastern Caribbean, Puerto Rico's landscape encompasses mountains, underground caves, coral reefs, white-sand beaches and an incredibly massive rain forest that supplies fresh water to most of the island. At the same time San Juan, the capital of the commonwealth, is a big city with a bustling business district, glitzy resorts and casinos, as well as one of the most stunning examples of colonial life in the Western world.

When the Spanish closed their colonial fort on St. Maarten in 1648, a few Dutch and French soldiers hid on the island and decided to share it. Soon after, the Netherlands and France signed a formal agreement to split St. Maarten in half, as it is today. Philipsburg displays its Dutch heritage in its architecture and landscaping. The island offers endless stretches of beach, beautiful landscapes and great shopping.

Tangier, a Moroccan port on the Strait of Gibraltar, has been a strategic gateway between Africa and Europe since Phoenician times. Its whitewashed hillside medina is home to the Dar el Makhzen, a palace of the sultans that's now a museum of Moroccan artifacts. The American Legation Museum, also in the medina, documents early diplomatic relations between the U.S. and Morocco in an 1821 Moorish-style former consulate.

Formerly a sleepy Spanish city, Barcelona has recently been reborn as an eclectic fusion of the modern and medieval. Seek inspiration from the creations of its modernist architect, Antonio Gaudí, or the Picasso Museum. Or, take in the breathtaking cathedrals in the Gothic Quarter.
