I guess what I find interesting is seeing resorts with strong "brands" like Sheraton and Hyatt being negative, in choice locations like Key West or Orlando, it does make me wonder if this could happen with some of the less desirable resorts location-wise like OKW. But, trading into the system would probably allow you to retain value.
I suspect, if it were to happen we would see it primarily with 1 Bedrooms, which already struggle against cash rates, and where, at times discounted cash rates through disney actually beat out point rental costs. So, it isn't negative for owners yet, but it could be, especially if Disney needed to discount the rooms more heavily in a future year.
We used to own two timeshares with Hyatt Vacation Club, and I can tell you from first hand experience that Hyatt "going negative" was very much a self-inflicted wound. Its not an inevitable fate of timeshares. For Hyatt, it was the result of some very poor management decisions.
I will leave some details out, because it gets confusing but here's the gist. In the old Hyatt system, you owned a specific week (say week 18, last week of May) in a specific unit (say unit 301) at a specific resort (say Hyatt High Sierra Lodge, a resort in an upscale part of Lake Tahoe right on the lake). You could every year use that exact week, or trade it for another Hyatt timeshare, or trade it through Interval into other non-Hyatt timeshares. Trading through Interval was a blazing good value, you could trade a 2 bedroom week into 3 weeks of studios, no problemo.
Then Hyatt Vacation Club purchased the exchange company Interval International. Nothing changed.
Then Marriott Vacation Club International purchased Interval International. (Yes, the Marriott timeshare system owns the Hyatt system, despite the different brand names.) Marriott VCI also purchased the Vistana timeshare system. Which means that MVCI now owns Marriott, Westin, Sheraton, and Hyatt timeshares AND the exchange system they use, Interval International.
This as you can imagine did not turn out well for the consumer. The MVCI version of Hyatt Vacation Club decided to take the lazy route. Instead of building more timeshare units/resorts, they invented a points product called Portfolio points- which is based on NO real property. Meaning there's no real estate behind it, you don't get a deed to anything. The points are expensive. If you actually read the sales contract, you are buying almost nothing for tens of thousands of dollars- some supposed booking advantages. The "product" sounds like you're buying that forever, but the contract actually says the Hyatt Vacation Club is committed to providing the points benefits for only TWO years. The points have no resale value. You may MF forever. Its genuinely absurd.
To actually provide a product for new Portfolio owners, they needed existing owners to buy Portfolio points and become part of the system. Then Hyatt could have access to booking my very nice owned week in Tahoe, say, and let me use something in the Portfolio system. But the only weeks in the Portfolio system were junky off season weeks owned by Hyatt themselves (because they'd foreclosed on these valueless weeks at some point) or Hyatt owners that owned junky off season weeks and bought Portfolio points hoping to upgrade into nicer weeks (that weren't actually in the system).
Then Hyatt relented and let existing owners trade into the Portfolio system so at least that one year they could provide use of your nice week to a Portfolio owner- but they weirdly made it prohibitively expensive, so not enough owners availed themselves of the opportunity. So they still had no good inventory for the Portfolio owners.
Then because Marriott also owns Interval (remember they own Hyatt Vacation Club too), they took away the sweet deal for Interval exchanging (to try to force these exchanges into the Portfolio system) but that is not going too well either.
At every step of the way, Hyatt Vacation Club forced more and more existing owners out which meant that HVC themselves owned more and more weeks- many of them junky because these are the owners who bail first. Portfolio owners also walk away as they realize they cannot book desirable weeks. This increases costs to HVC (because they have to pay the maintenance fees on all of those weeks, regardless of their desirability)- this led to dramatic year-over-year increases in MF and accelerates the exodus of existing owners.
So in a relatively short period of time (5 years maybe), the majority of Hyatt weeks went "negative" but not through market forces- it was through the deliberate actions of the management company. I personally bailed early enough that Hyatt bought my Tahoe week from me and took my Carmel, CA timeshare back for free (now they charge people a fee to take a week back). So I made out ok and got back maybe a third of my original resale investment after using the heck out of my Hyatts over a decade or so.
tl/dr basically the
DVC version of this would be if DVC invented a product called Malarkey Points and tried to sell it to you for $40,000 + additional annual dues. They explain that Malarkey Points give you the rights to book at ANY (available) DVC resort in the Malarkey system at the six month mark, and at 11 months you can book ANY (available) POINTS in the Malarkey System.
If you are left totally perplexed by all of this and confused why anyone would buy Portfolio/Malarkey, its not because I've failed to explain it properly. Its because it literally makes zero sense.
