Googled it cause that question actually got me curious. But, ya, you should stay far away from this. As everyone has said.
From your article, like 3rd comment:
'My parents did something like that maybe 2-3 years back, and my dad tells the story a lot at family functions (so may be slightly "dad" exaggerated). They were offered tickets to a local concert (about a $250 value) if they listened to a 90-minute timeshare presentation.
My dad said that they had everyone (30 people or so) sit in an auditorium, and once the presentation started, the entrance door was closed and there was no handle on the other side so you couldn't open it from the auditorium. The only exit was a fire door that had a big sign, "EMERGENCY EXIT: ALARM WILL SOUND WHEN DOOR IS OPENED".
After about two hours, my dad actually stood up and interrupted the presentation, said that he had stayed the full required 90 minutes, and would like to leave now. The presenters insisted that they were almost done. After another 30 minutes or so, my dad stood up again, and said that he would like to leave, and if they would not let him leave, he was going to call the police for being held hostage.
At that point, they let my parents leave with the tickets. My dad considers the experience a success, my mom was absolutely mortified and said she would never, ever do something like that again.
So moral of the story: you must have a thick skin and read the conditions carefully, and insist on leaving once you have fulfilled your promised "time"."
Well I can thank IE for my fully matured thick skin. Sounds like I'm the perfect person to capitalize on something like this.
