Timeshare packages to save $?

[d4est]

I posted this on the budget board but thought I might have some luck here.

Has anyone ever stayed at a timeshare resort to save? I am talking about ones like Sheraton Vistana Villages or Embassy Grand Beach Vacation Resort. The deals offer deep discounts on a room (sometimes 1st night free) such as $59/night or:

3 Days/ 2 Nights Only $149! (Additional Nights Only $75) 1 Bedroom Luxury Villa Plus Your Choice of 2- 1Day Pass at Disney, Universal or Sea World

They all seem like nice places. You just have to agreee to doing the 90min tour of the place. Seems like a good way to get nice accomodations for little $. We have done a tour before for free tickets. We don't mind the hassle.

Just wondering if anyone else has tried this.
