Sanctuary Cap Cana is one of the most unique resorts in the Caribbean. This is the only resort where you can actually stay in a castle. Rooms come in many different varieties such as swim-up suites, private plunge pools, private villas, and private island rooms (yes you heard that correctly). All castle rooms feature butler service (ask for Emilio). The Sanctuary features Spanish-Colonial theme throughout the property and has several pools, restaurants, and bars.
