I will comment on where points programs I know fall. Others can add Marriott, Hyatt, and others where they see fit.
There are 4 types of points systems AFAIK.
They don't really affect how points are used in regular season usage, except for Home week usage, but they do vary on how MF/point are determined.
- this is like the Worldmark system, (parts of the Wyndham are now sold this way and they belong to Club Wyndham Access (CWA)
) . Worldmark was set up where only credits are sold and MF is the same for every credit in the system. Some WM memberships have an added fee for a feature called Travelshare.
Resort Based Points
- Parts of Wyndham properties are sold like this - it is like pure points, in that you own an UDI - UnDivided Interest in Points currency. Since your MFs are resort specific you belong to the Club Wyndham Select (CWS)
type of membership. Your MF are based on WHERE points are owned. However MFs are NOT standard across the entire system, they are RESORT SPECIFIC. There are variations, some resorts have better MF/point costs. I believe DVC is also like this.
Resort Based Size/Season Points
- this is what Hilton Grand Vacation system is (Legacy parts of Wyndham is this way, and there is it called Converted Fixed/Float Weeks, and they are also part of the CWS type of membership). They are all sold as fixed or floating weeks for a given size and season of unit. MFs at a property are the same for all the same size units regardless of season. However points are awarded by Season and Unit type owned. So MF per point vary. Seasons are Platinum, Gold, Silver and Bronze in HGVC. It is better to own Platinum as your MF/point are the lowest possible. Bronze week ownership could result in MFs/point that are 4 times higher than a Platinum week in the same size unit.
- Wyndham is the king of hybrids as they have all of the 3 types above in one system. Hybrids could be any combination of the above choices. CWA is now sold as a Pure Points
where there is a common MF/point. (It is made up of converting older resort inventory obtained and converted to CWA and MFs are just a blend across all ownership deposited into CWA.) Wyndham has CWS that is either Resort Based Points
(UDI points) OR Resort Based Size/Season Points
which is essentially converted fixed/floating weeks in points). Club Wyndham Presidential Reserve and Club Margaritaville are also Resort Based Points
CWS, but these are also a club within the Wyndham Club. They get special perks at their club within a club that the rest of club wyndham has access to in different time increments, if at all.
Since you can buy any of the parts of Wyndham today (and also UNCONVERTED FIXED and FLOATING weeks, that while Wyndham, they are NOT wyndham points and are usually too expensive to convert), it is very important to know what type you are buying if you are interested in obtaining Wyndham points.
Here is Wyndham's definition of the part that make up Wyndham :
Four products have access to the CLUB WYNDHAM Plus exchange program, each with unique attributes that appeal to different types of owners.
