The U.S. Virgin Islands is marking 100 years by giving $300 in spending credits to visitors.

According to the U.S. Virgin Island’s tourism site, the credits can be used for historical/cultural tours and activities. The reason for the promotion is that 2017 is the 100-year anniversary of Transfer Day, the day in which control of the islands was formally transferred from Denmark to the United States. The U.S. purchased the islands in 1917 for $25 million in gold, seeing them as a strategic location. GO HERE to learn more about Transfer Day.

To qualify for the spending credit, trips MUST be booked on the island’s official tourism website and travelers must spend a minimum of three nights in a participating hotel on St Croix, St. John or St. Thomas. Trips must be booked before Oct. 1, 2017 and the travel window is listed on the site as Jan. 2 to Dec. 31, 2017. The tourism site added those who book on the site and travel in March would also receive a “Commemorative “Centennial” Souvenir.”
