Wyndham could still offer those benefits, guaranteed, with specific brands. A "based on availability" early check-in/late check-out benefit is nearly worthless unless I can guarantee it somehow in advance. Hotels could be required to have a certain percentage available for early check-in or late check-out online when someone's logged in as an eligible member. It could even be tied to specific brands, so hotels that don't want to offer the benefit could still be part of Wyndham, just as a different brand. (For example, maybe Ramada and Howard Johnson have it, but Days Inn and Super 8 don't.)
I get that Wyndham may not want to put that pressure on their hotels, but until they do, any on-property delivered benefits are too hit-and-miss to be a selling point. With other reductions in the program, it becomes much harder to justify being even semi-loyal to Wyndham brands.
