Most time share presentations take about 3 hours, and yes, you do have to be rude to say no. To make saying no easier, see the Disney Vacation Club. Our first time, we said no and were out in 35 minutes. Also, after seeing disney, you can compare to the other timeshares out there. We bought DVC, but we still listen to other presentations once or twice a year. Sometimes, the perks are pretty good. For instance, at Williamsburg, VA, I had to reserve for $99. We got two nights at a hotel(sleep inn), breakfasts at the hotel, a coupon book, two adult passes to Williamsburg ($60 for two), $30 for dinner at one of 6 restaurants, a $30 gift Certificate at an outlet mall(got $15 sandals and 15 cash back) and $50 cash after we heard the presentation. Since we had always wanted to take the kids there, it was worth it for us, and the DVC still seemed to be a better deal.
