I went to a presentation last week at the Marriott Vacation Club in Hawaii (Oahu) and they were very laid back, no pressure at all.
It's a great concept and makes sense. Only issue I have is not being able to earn MR points on stays while using your club points but the ability the transfer club points to MR points is a big incentive.
They were also offering, in addition to the 10,000 points you get for attending the presentation, anywhere from 275,000 to 975,000 points (depending on the package) for signing up on the spot. So no hard sale but some pretty attractive incentives!
