So the Board is asking you to pay the maintenance fees despite telling you that the resort is closed. Poof. Gone. And telling you that you won't be able to stay for even a moment of time in 2025.
But on the other hand, not giving you any sense of what the likely payout will be later on.
That's what's called, in German, someone offering to sell you a "katze im Sack (pronounced Zahk)" (a cat in a sack). "I'm offering you this incredibly beautiful cat for such a good price, you won't believe how nice this cat is" (but won't let you see the cat).
I would think, if they're going to get anyone to go along with this, that they would provide you with all manner of likely outcomes, the most likely as well as the extremes both up or down from what they believe is most likely. And PROVE it to you by suggesting what prices they're discussing with the prospective purchaser.
Instead, nothing.
So I wouldn't feel good about this. The know they have to provide you with complete information. If it were a new stock Initial Public Offering, they'd have to provide you with a prospectus revealing EVERYTHING.
It seems to me that, if they're unwilling to enlighten anyone, it's time to speak to a Massachusetts state attorney (such as an attorney in the Attorney General's office). Don't allow yourself to potentially be scammed.
