1. They lure you into 2 hr sales presentation by offering free tickets and hotels (Which later I realized are not very good)
2. They make you go through a presentation highlighting how their service is much better than traditional hotels. They talk about inflation and how your money is being wasted using hotels for vacation. (May be using some fancy terms and numbers to influence people)
3. They pair you with an individual sales rep, who tries to sell you. They highlight benefits, hiding all recurring cost associated with it. Emotionally pressure you into accepting the fact that you are not taking enough vacation and how you are not caring about you and your family's need.
4. They focus on the fact that you "Own" it without explaining how you own anything.
5. They force you to make decision right then and there. Because the sales agent know that if a customer is interested in buying it there are much better pricing available in secondary market if they do some research.
He gave me these reasons: they are expensive and charge you assessments every year which can be raised at any time (like a condo), but unlike a condo, you can't sell them because nobody wants to buy them. You can't even give them away, so you're stuck with them for the rest of your life. You can't even get rid of them by declaring bankruptcy.
Unethical but legal. Depends on your definition of scam.
Collective ownership of a holiday property can be enormously effective. If say 8 people co-own a property, then you have a getaway for a week, or just a weekend/long weekend every couple months.
Alas with hard-sell timeshare you don't really own it. (if you did you could just collect all the other shares, and sell it as a house.) In this situation buying forever obligations seems like a bad idea.
