The Marriott Vacation Club Destinations® Exchange Program is now called Abound by Marriott Vacations™. Through affiliation with the Vistana Signature Network® (VSN), Abound will allow for more direct access to Sheraton® Vacation Club and Westin® Vacation Club resorts — all using the shared vacation currency of Club Points.
