FWIW, with all of the hotel-associated timeshare systems I've looked at, the hotel elite status and and timeshare stays are almost completely separate.
The exceptions I've noticed:
1) With several/most, a sufficiently large developer purchase will get you elite status with the hotel.
2) With Marriott, timeshare stays count towards elite status (for instance, a 7 night stay gives you 7 nights of credit towards elite status).
I haven't seen ANY where having hotel elite status gives you ANY benefits or perks when you stay in a timeshare.
