I own Wyndham points and Wyndham Fixed Weeks. I own Converted Fixed Weeks to Wyndham points (weeks still considered Fixed Weeks but are at Wyndham resorts). And I own weeks NOT associated with Wyndham but which are PIC'ed to give me MORE Wyndham points. And I own weeks not associated with Wyndham in any way shape or form.
Confused?
Does NOT depend on where you own to convert a week to points; it must be a fixed week at a resort where they managed THAT inventory. What depends is if you are buying more points from the developer or NOT. No purchase, it will cost you about $1500-3000 per week. Buy some many NEW (full price points), $189 per week (up to 2 weeks) for 1 developer purchase of 126K of new points.
As for different types of points --- UDI points, PIC'ed points, CWA points and converted fixed weeks ... at the 10 month mark (ten months before the check in day) ... all points are equal. Before 10 months, it is mainly what you can reserve and where (Advanced Reservation Priority window).
