But with the opaque division of inventory, rights and priority of booking are not taken away from an existing week owner to book at what they own. I am not understanding the last sentence.
To be more explicit. There are X weeks in a particular season. Furthermore, in every season, some weeks are in higher demand than others. How are the weeks divided between weeks owners (as a group) and points owners (as a group)? How does the splitting occur? Totally unknown. Does the DC trust "cream" the best weeks for the trust use? There is an inherent conflict between allocation for points owners and weeks owners for allocation of inventory.
I will give my real-life example. I was a single week Red (Platinum) owner of a Royal Palms. (Purchased resale, after 6/2010). I also has been given a White (hurricane/mud season) pre 6/2010, which I had enrolled in the Trust. In the particular case, I could book in May (low season) with the points from hurricane season. (Points system quirk.)
So at the 12 month window (no 13th month for a single Platinum week owner), I tried to get in. I missed the window by around 5 seconds (early) and couldn't get in for another 40 minutes. At which time the only Platinum season weeks left were in August. (I had been trying for Jan/Feb). 3 weeks later, my brother (a co-owner) called Marriott about the available choices. The response was most interesting. I could use my Trust points for the year in question and the next year can get the exact (high demand) week I wanted. No problem, they had lots of those unallocated weeks for my resort. . . (But no weeks inventory. . .)
So why could I not get it with my weeks but could get it with points? Well . . . . how is the inventory allocated? Clearly the DC Trust got the weeks before I could at 40 minutes in.
It was obvious that as a single week owner, I would always be at the last of the line. (II trade? More money for a maybe trade, to get what I couldn't get in the first place as an owner? No, not acceptable.)
Therefore, I sold back to Marriott, for almost enough money to buy at Bay Club in Hawaii. In the HGVC world, owning something means you get first crack at your ownership inventory, only competing with those owners who have the same ownership you do. Not being last in line. . .
