Went to a timeshare presentation back in the early 90's when staying @ Dawn Beach (for those who don't know is now the Westin). If we took the presentation we got a free car rental. Ended up buying a week which I then canceled the following day. It was either that or be returning to the states single. The other couple we went with bought there the following year only to loose it to Hurricane Luis in 1995. It was never rebuilt due to insurance payments that were never forwarded by an agent and other owner problems.
When we stayed at OBBR sometime in the 2000's we took another free presentation to get a free dinner out of the presenters. The couple that lost their Dawn Beach timeshare was also along for the ride. When we reached the point of signing up they of course refused and us as well and told the presenter why. At that point she realized she was at a dead end. Gave us our meal tickets and we were on our way.
