There are three kinds of ownerships at resorts managed by Diamond Resorts International (DRI) (formerly Sunterra).
-Own a deeded week at a resort managed by Diamond. Resale owners at any of the Diamond resorts own only at that single resort and can’t use points to go to other Diamond resorts.
-Own “Trust” Points. Resale owners of the “trust” are allowed to use their trust points to reserve time at any of the 19 resorts in the trust. But not at any other Diamond resorts. ( to use the trust pts at other diamond resorts, you must have purchased the trust points directly from Diamond-Sunterra)
-Be a “CLUB” member and use your points to reserve at any of the Diamond owned resorts and also the many Diamond affiliated resorts managed by Raintree and Vacation Internationale ( subject to significantly limited availability) . To be a club member, you must have purchased your ownership directly from the developer. Although it is possible to buy resale then buy more from Diamond and have all your resorts/points brought into the club.
