When Diamond took over Gold Key in Virginia Beach, the pitch was to trade in your deed and purchase points. A lot of people regretted that. Those that kept their deeds were happy they did. The pitch to pay maintenance fees with points is a BIG selling point with the unscrupulous Diamond sales guys. It doesn't work. I'm sure that he did not put this in any written form.
I've heard them rhapsodize about how wonderful it is that we can monetize our points. - use them to pay maintenance fees, book hotels and flights, etc. etc. That is one of the tremendous values that one gets by becoming Gold, and it's even more wonderful if you go to Platinum because your points have value when you are platinum (or higher yet).
If I respond at all, I ask them why I would pay $1000 in maintenance fees using $2000 in points. And that every time I've looked at using my Diamond points for other services, I have always been able to make the same reservation directly for less money than those Diamond points cost me.
One sales guy agree with me, then said it probably worked best if you did that using points that were going to expire anyway. To which I replied, that if you monetize Diamond points, you can't use current year points. So you can't use expiring points that way any way. He said nothing, but the look on his face was eloquent. I don't think he knew that limitation existed.
