This is definitely happening, and it is NOT just 2042 resorts. The 2042 resorts are if anything exceeding reality due to their prime locations.
Location is why monorail resorts have much better value than SSR or AKV, for example.
In the end though, the 2042 date is a certainty. No matter how great the location may be, it's not worth paying more for DVC than one would pay for a cash room, for example. (No, we aren't in that situation yet. But that represents an absolute ceiling).
What is Disney’s goal? Riviera resale is starting to show where reality is for that product.
Premature to judge Riviera. It's actually exceeding most other resorts in resale as a percentage of direct price. And resale is always cheaper when a resort has no ROFR.
For January 2023, Riviera resale prices were higher than AKV and BWV.
It will be several years until we can judge how Riviera truly performs on the re-sale market, after it sells out and starts to get ROFRed.
It is considerably less valuable on resale.
It's 38% cheaper than non-incentivized direct. BLT is 40% less than non-incentivized direct. Poly is 38% less than non-incentivized direct.
So it's actually about the exact same as the other 206x resorts. Grand Floridian is the only outlier (at 25% less than direct). Meanwhile, the truly less valuable resale resorts are OKW (50% less) and BWV (45% less).
The Galactic Starcruiser is not working well for them at all. A Star Wars themed hotel with the equivalent of the Polynesian luau might have worked - but the product they are creating is too niche and too expensive to support long term. I suspect that building will be rebranded or the experience will undergo significant changes in a few years. DVC may be a part of that repurposement as well.
Like all things, it's supply and demand. They overestimated the demand at the price point. Some re-adjustment, it will likely do fine. I expect them to increasingly "package it" with as part of a weeklong trip. (Instead of $5000 for 2 nights for a family on the starcruiser, it will be $8000 for a 5 nights at the Grand Floridian + 2 nights on the Starcruiser).
