I just left Vegas from a four day stay and it seems some of the dedicated rewards desks are going away and things are just handled through the "cage" (aka, cashier, where you cash in chips). This was the case at The Flamingo and Horseshoe (formerly Bally's). Not sure if it's company wide but I kind of get it. The folks at the rewards desks did just sit there twiddling their thumbs 95% of the time.
