I think someone should suggest it to Adam Burke. I'm only a gold at Hilton, but maybe he'd listen to a Diamond? It is possible that Hilton doen't make enough money off the restaurants to encourage non-guests to eat at them--that's a possibility. But if it made sense for them economically, I'd like to see Mr. Burke adopt it.

PS--Anyone want to volunteer contacting Mr. Burke? (I'd let you put my name to the letter).
