Lol. Do you mean people who have essentially inherited their parents DVC?
Not really talking about financing. My analysis uses cost of funds (i.e. time value of money) to discount future cashflows to present value. This is separate from the inflation rate used for either hotel prices or dues. From the mid-90s through to the mid-00s, I'd use 5%-8% as this rate. I'd usually explain it as, "If you took the cost of buying DVC and instead bought a treasury bond, how much interest would you earn each year?" Fast forward to anytime after 2008 and you're looking at 0% to 3%.
So for example in 2005, you could take your $20k, put it in a money market account, earn $1000 a year, and it would pay for half of your $2000 resort stay. Fast forward to 2015 and that $20k in a money market account would only earn you $50 a year, so buying DVC looks more attractive in comparison. [Note: That's not my actual analysis, but that's the kind of thing I'd say if I was a salesperson. As I said, I incorporate this rate into my DVC spreadsheet by discounting future cashflows.]
Back to the original topic of room prices, I'd expect them to be roughly similar to room prices at the Wilderness Lodge.
