People do different things. I bought 1000 points when the program first started. It was the minimum that I could buy. Do I regret buying? Not really. But at the time there was no resale market as it was new. It sure would be nice to have been able to save $5000 or even $6000 in the resale market, but I just included it as part of my learning fee. But if you were talking about buying a larger number of points, I would hesitate and evaluate a little more.The ability to exchange points with other members is what makes the program work. If people didn't buy points from Marriott, our exchanges would be a little more limited. The piper always gets paid in timeshares.
