Some timeshare presentations are more high pressure than others. Although I do have to say that when we did ours, it took 4 hours. We in the end bought into it, because we were in the market, but this year, we thought about upgrading, and I told the salesman up front. I have things planned today, I don't want to spend the whole day here.
The tickets are more than legit, some give actual money. Just make sure its FREE, and not discounted. I was under the impression the tickets were free when I agreed to do the upgrade this past summer, and they were not. Just double check it. If you are not into wasting time, keep an eye on the clock. Its only supposed to be 90 minutes. I started to get antsy since I did have other plans, and told the salesman that I had to get going, and lets get down to the paper work. Another suggestion is to eat before you go, another big time waster. They offer a free breakfast, well don't bother, that time spent eating is not accounted for into the 90 minutes. I did grab a cup of coffee, but that was about it.
If you have any question, feel free to ask! Enjoy!
