When I checked in for a stay using Free Weekend Night awards, the "Welcome Desk" clerk (it was a W) actually wrote my Starpoint balance on my keyholder.
I'm not sure if this is a new thing, something to do with W's
StarGuest tracking system, or just a slight misinterpretation of a policy like “on an award stay, write the number of Starpoints instead of the rate”. In any case, the hotel definitely had access to my Starpoints balance. Which makes sense if they offer Instant Awards.
(I also had this happen at a Holiday Inn once, with IHG's version of points, on a paid stay. Maybe it's a new hospitality industry fad?)
The back of the keyholder had this information about
StarGuest:
