Timeshares: Scams or Investments?

My wife loves free things. When we go to any expo at the Hawaii Convention Center or the Blaisdell, she’ll be the one hoarding free pens and reusable bags. So, I should not have been surprised when she stopped at a table run by a hotel chain that was offering a free dinner, six hours of validated parking in Waikīkī and a two-night stay at a hotel. According to the salesman, all we had to do was review a hotel from pictures they would show us. The whole process would take only 120 minutes (not two hours?).
