If I were Marriott:
Anyone could reserve any week at any resort as long as Marriott still has points units avaiable at that resort. For an example: Marriott gives Joe 1200 points for his plat MMC. Joe has no need to resurve any week at MMC unless that is where he wants to go to MMC. If he does want to go to MMC his 1200 points is enough for a two bedroom 7 night stay any week during platinum season. Joe would reserve the week he wants by going on-line or calling the "Points" reservation line just like he does today on the weeks system.
If Joe wants to go to KBC over Christmas he calls the points reservation line one year out and trys for that week just like people who bought there. If all Points for that resort are already used up he is out of luck. If points are still avaible he has the right to reserve his time there, as much time as he can get with his points. His points will go farther with a one bedroom than a two bedroom, but that will be his choice.
He will be on the system trying to reserve with his points just like weeks owners will be trying to reserve. Weeks owners will only have access to the number of units still in the weeks program for a given season and points owners will only have access to the number of units in the points system for that season at that resort.

This is essentially how most points based systems work with the exception that there is a home resort reservation advantage. One system we own in give a 2 to 3 months advantage, the other gives a 3 month advantage. In this way owners of their home resort have first shot at getting the weeks they want prior to having to compete with all other owners.
Both systems have some sort of agreement with Interval or RCI as to what type of inventory they give to the exchange company for external exchangers. By having this agreement, the points have a value for exchange through the exchange company.
One system (Hilton) has a set value for points taking into consideration season, view and size of the units. It doesn't matter if you own in Hawaii or Orlando, a two bedroom Platinum season costs the same amount of points.
Most systems seem to vary the number of points by resort. DRI has different values for different resorts. One Vegas resort's two bedroom unit requires 12,500 points for a 7 night stay in the two bedroom unit. Another requires 14,000 points for a 7 night stay. Some resorts around the world cost as few as 6,000 points for a 7 night stay.
I'll be interested to see if Marriott goes with the fixed points depending on unit size, season and view or, if they'll do like most and go with varying numbers of points based on individual resorts. My bet is they'll go with varying numbers of points for each resort. Personally, I'm not in favor of this sort of system but, it allows a developer to continue to try to sell owners more points as the newer resorts go up in points cost. Since it gives current owners a reason to continue to buy more points, it's an advantage to the developer to use this sort of system to churn more business out of existing clients. That's the only reason I believe Marriott would use this type of points based system rather than a system with a fixed value system.
