You will be treated the same as any other Club Wyndham owner - which is to say that you will constantly be misled and harassed to buy more points.
You will receive an allocation of housekeeping credits that should cover you for 1-2 reservations, so you generally will only pay housekeeping fees if you use your points more than that for numerous short stays. You also are likely to run out of free transactions if you use lots of short stays.
You will automatically become a Club Wyndham Plus member when the timeshare is transferred into your name.
Before committing, it is in your best interest to determine exactly what you are buying, and what (if any) points will be in the account when it transfers to you.
