Really don't need a broker ... just get on eBay.
Your friend should have some idea as to WHERE they will need ARP (advance reservation priority). That is their HOME RESORT or to pay MORE for CWA points which MIGHT get them the ARP which that CLUB holds.
Your friend needs to look at the ONLINE Member's Directory ... see how many points it will take to book a UNIT for a week where they most likely be visiting. Shame to buy a 105,000 points when you need a 126,000 points to book your dream stay. (and those values would be an older resort's PRIME week or in the Value Week in a NEWER resort).
Friend should buy in increments of 77,000 points and WAY MORE, than 77K. (ie 154,000; 231,000; 308,000) as transaction credits and housekeeping credits have 77,000 points as their multiple. But check the points charts.
Always check the MFs in eBay ads with the current fees for the resort ... some older resorts, the MFs are based on the underlying week's MFs .. which is the same for ALL seasons. So a PRIME week converted to points has a WAY better points to MFs ratio than a VALUE week converted to points.
There is a TUG PRIMER for Wyndham written several years ago ... your Friend needs to study it and understand it. Lots of terms (vocabulary) but using the system involves LEARNING SOME of the details.
Some/a few Wyndham resorts still offer DEEDED points owners there, Day Passes to use the resort. Shawnee is one ... which is WHY I hold a deed there.
One saying is: buy Wyndham for $1000 might cost MORE but buying a cheap Wyndham for $200 with a BAD ratio on the point to MFs.... the $800 you saved when buying will be totally GONE inside of a couple of years ... the added expense will be ONGOING until you can dump the "dog" deed.
PS My one Shawnee week are in PRIME season and converted to points with CWP fees is $4.47 per K. The other gets me a few more points and its ratio is $4.27 per K.
My Royal Vista points are $6.44 per K. So my million plus Royal Vista points cost me $2170 more YEARLY than if I own the cheapest of my Shawnee converted weeks for a million points. Every YEAR ... paying $2170 more in MFs based upon where the deed is.
