IMO converting anything less than platinum into points is not a good deal as you get less points for almost the same MF charges. It would appear that Marriott won't exercise their ROFR on this resort for a gold week, which might mean your best option for fast results might be Ebay, but be prepared to take a huge loss. I'm not aware of any resales that come with the points option unless you purchase the resale from Marriott.
I think the enjoyment and real value of points comes after the kids have left the nest and it becomes time for the parents to see the world rather than feeling cooped up in a 2 bdrm timeshare where half of the space is wasted...and when it's really nice not to have to make your beds and get turn-down service, to phone for breakfast room service, to be entertained in the hotel bar and restaurants, or to walk out the door onto Via Veneto, Champs Elysses, Westminster Bridge, etc. Realized dreams from Marriott Reward points in first class hotels that charge as much as $600 a night -- and if you get Marriott air/hotel point packages you get the air too!
Still, you have to look at how many points you get for how many dollars to assess the value -- and in most cases platinum is the only type where it's workable. At Manor Club you get 110k pts for $607 MF (plus fee) which would take you 55 hotel stays at $200 a night to earn. However, the same number of points from trading in BeachPlace costs you almost $1000 so it becomes far less attractive an option.
