We bought when diamond was Sunterra, when we upgraded to the unique udi points we signed having a grandfathered in clause using our home resort 3 bedroom anytime for 8000 pts. We had the salesman write it personally on paper for us. We always have to call for the reservation and they find the clause in our ownership. No problem honoring this for 20 yrs. Any others have the same? Experience with new ownership?
