OK, I'll play. Let's buy 1M Bonnet Creek points for free, as there are multiple listings close to free. Let's ignore the transfer fees or activation fees or whatever games. Dues are $7,500/year. For DVC SSR, using the board sponsor cost, $11/point/year, that translates to about 680 SSR points/year.
Lets go to the charts and pick late August. Bonnet Creek gets 4.3 weeks in August in a 2BR presidential vs 2.2 weeks in 2BR SSR. Bonnet Creek doesn't have studios, but it gets 7.9 weeks in the cheapest Bonnet Creek unit vs 6 weeks in a SSR studio.
Bonnet Creek is a lovely property, and maybe Wyndham is a good choice for many, but it's not 1/5 the cost, and it isn't like reselling DVC. Though writing this out is making $3,500/mo rent for a Wyndham vacation property sound pretty nice, if you wanted to lock this much up in a timeshare commitment, assuming you can even make bookings, like I know you could with DVC.
Edit to add: You can also rent the other timeshares as well, and that looks like an even better plan. I do hope to stay in Bonnet Creek sometime. Its thread is always popping up, and people seem to love it! And wow, 100-150/night to rent a 2BR!
