5 years ago I rented additional points for a large group of family members for our 50th anniversary. I went though The Time Share Store (a Intercot sponsor at the time). As I was a DVC member it was handled as a transfer of points. I asked for and paid for Old Key West points but what the owner of the points transferred was 35% OKW and 65% Saratoga Springs points. As the agency handling the transaction The Time Share Store was unable to do anything to correct the error. After many hours and very understanding member service cast members I was able to correct the problem.
Would I ever again rent points? Oh, heck NO.
