Though some believe Aulani's value won't hold up, the data indicates that it is just as likely as any other legacy resort that has 30+ years left. I've seen many of the same theories - spread out over many years - repeatedly popping up to try and explain why Aulani's value continues to rise despite predictions to the contrary, but the bottom line is that it wouldn't sell at the prices it does if people weren't willing to pay.
As someone who once sat on the Data User Advisory Committee of the BLS, I know a little something about economics, and though I have no delusions that this is some kind of wise financial investment, I've taken a look at the data and done enough research to conclude that
DVC is no Wyndham or Marriott, and similarly, that Aulani is no HH or VB. In other words, I've already concluded that the likelihood of losing a lot of money on this is fairly low, while the value I find in it exceeds the value I would find using that money in other ways. I have no debt. I have money in the bank. I have a very sound retirement plan that includes healthcare for life for me and my s/o. And right now, I want to buy into DVC with access to all legacy resorts, get the most points that I can given the amount of money I'm willing to spend while still remaining at a relatively low total cost per point per year (the contract I just entered puts me at $11.54, about a dollar less per point than I could reasonably expect to get AKV right now while trying to outbid ROFR).
To a certain degree, gotta just say to each their own, you know? I'm buying DVC for a lot of reasons, but an 11 month booking window is not one of them. I know it matters to others, but no matter where I buy I would rarely plan a vacation more than 7 months in advance. In a lot of ways that kind of planning is not practical for my life. The argument you're making is coming off as though the only value in DVC is if you're willing to plan that far ahead on a regular basis. Do you really feel that way?
