This is all, of course, currently in the realm of speculation, but the "enrollment to save on fees" cannot possibly be a free lunch. There has got to be a big hidden cost to it or Marriott would not have done it - they did not go through all this effort just to subsidize II exchanges. We just need to figure out what that hidden cost is it is...
Dan,
I don't believe it is a hidden cost (to us), I believe it is a hidden benefit (to the DClub).
I believe that enrolling in DClub and then making trades thru II gives DClub a first pass to make your requested trade, giving Marriott the option to keep your week for the DClub instead of passing it along to Interval and to some random Marriott owner.
I've used this example before -- and if it doesn't work this way, Marriott missed a major opportunity to snag prime weeks.
Let's say that I want to trade my 3BR MOC week for a 3BR at Ko Olina. I call my Marriott VOA and say that I want to make this trade.
Marriott Trust has tons of 3 BR Ko Olina units in it -- I believe they would make that trade using Trust Inventory and take my MOC week into the Exchange Pool. Or maybe, they make a second trade simultaneously with Interval International providing the desired 3BR Ko Olina week, and then Interval has agreed to trade my 3BR MOC back to Marriott.
If they didn't, is Marriott really going to let the 3BR MOC go into II's inventory and just sit there?
So, I believe a major reason for the free II trades is to give Marriott a first look (Right of First Refusal concept) at inventory before it gets deposited into II.
I posted this theory before and it was criticized as too manual and labor intensive -- but I believe criteria could be established to make it very very simple -- ie, any 2BR or larger at a TDI property greater than 130 and the unit never makes it to II.
I would be very surprised if Marriott hadn't implemented something like this, but I have no evidence that the arrangement actually exists.
Best to all,
Greg
