Here's some of the perks I mentioned in my other post with Marriott timeshare ownership:

-Points toward airline tickets.
-Marriott hotel stays.
-Cruises.
-Rental cars.
-More than 40 Marriott Vacation Club resorts.

And on the MVC website "...Choose from more than 2,000 spectacular properties in more than 75 countries through our exchange partner Interval International."

Again, we really enjoy our timeshare with Marriott and I'm sure Hilton has a great program as well. Hope this helps. Take a Marriott timeshare tour and see for yourself.
