I do agree that if you are in a pinch you can do a timeshare tour. I would just avoid Westgate. I've even done it myself. Only you can decied if the time is worth the investment.
You can sign up for Marriott at the hotel lobbies of the Marriott's in downtown dinsey (and probably all of them in the area) and for Hilton at the outdoor kiosk at the Premium Outlet malls.
I wrote a review several years ago on about 4 or 5 timeshare pitches and Marriott and Hilton were by far the 'winners" as far as no/low pressure and time commitment.
