Dean, you bring up some interesting thoughts. But I own at Marriott too, and a premium property at that. And I paid more for it than my 500 points with DVC, so one cannot use a broad stroke to say Marriott is cheaper. My dues are very pricey with Marriott as well. VERY. I can tell you as an owner of BOTH that I think the fees in toto are quite comparable.
As for the Destination Points and trust owners, I have looked at this option up one side and down the other and every single way I crunch the numbers it is an outrageously expensive option for Marriott owners IMO. For my family it makes zero sense. I would have to pay another $35,000 to $40,000 to get another week of what I already currently own. That is comparing apples to apples btw. I am looking at being able to book precisely what I generally book with the weeks I currently already own. And on top of all THAT, there are extra fees to be in that "sweet" little program. And they are high fees, IMO. So when you say "free lockouts, free internal exchanges, no add'l II fee, etc.", they ain't free. Not even close. Just like with DVC, you are paying for it. And as I recall my lockout fee for our trip this year was $85 not $75. I do not pay a "lock off" fee with DVC.
That is just the tip of the iceberg, Dean. Again, you make some good points but unless you own at Marriott, it seems unfair to make a comparison on hearsay. And let me tell you this as well, every single time I have tried to book my home resort w/Marriott I call the very first nanosecond the inventory is released. And I have had them tell me, "no availability", before. After paying what I did, I was horrified. This was NOT an experience I have had with DVC as a 22 year member. Can it happen? Sure. But when as a DVC member I call at the very first moment with my home resort priority, I cannot recall one time that I did not get what I wanted. And I generally am booking beach cottages at Vero or GV's on WDW property.
My dues are actually more with DVC than my platinum weeks with Marriott. Here's the bottom line from my point of view as owning at 2 different premier TS companies: I have to look at what my annual dues cost, and then I factor in a breakdown on the annual cost of the membership spread out over the lifetime of the membership. I look at what I can and do book with these memberships. Then I look at what it would cost me on cash. I can tell you with great certainty that I come out better so I am overall happy with my purchases. (Yes, I understand that my way of figuring value may differ from others, but I crunch numbers based on the way WE use our memberships.) Granted the booking windows and trying to get my Marriott at the times I want make me WISH I had known what I now know because I would have bought fixed weeks….
