Time share can be time-suck 

My time-share maintenance fees exceed $2,000 per year. While this does not cause a real hardship on me, I was wondering what happens to the time share ownership if the primary deed owner dies. When I die — I'm 80 now — I assume the time share points go into my estate. And, if they do, does that obligate my heirs to continue to pay the annual maintenance fees in perpetuity?
