CWA or CWS are your choices. Club Wyndham Access or Club Wyndham Select.
CWA is Not Deeded, you are sold points for a variety of properties, MF are blended across those properties. You get access to ARP (Advanced Reservation Priority) at all of the CWA Inventory at the 13 month mark.
CWS is Deeded at a specific Resort, these are either sold as UDI (un-Divided Interests) or a converted Fixed weeks. MF are just for the points owned at that specific property. You are given ARP at the 13 month month for ANY CWS inventory at that resort if you purchase UDI points. You are given ARP access to your deeded week ONLY if you purchase a converted fixed week.
At the 10 month mark all Inventory becomes mingled and it is available to both CWA and CWS.
NOTE they are still Fixed weeks out there that are NOT converted to Wyndham Points. You do not want to purchase these weeks if you are trying to get points, as the cost to enroll them into the points program is prohibitive.
