I have done this. We went to the presentation at the Vistana Resort last year. They gave us free food, let the kids have free access to the game room with all the machines and $100. I was actually interested to learn about how it worked. The dollars didn't add up and the sales lady seemed to be a little upset with me and we met "the boss". We will be doing this again at the HGVC this year. It is a pain but if you are having a down day at the resort, hanging by the pools, the 90 minutes can pay for itself.
