Honestly that's not a bad idea, but take it a bit further. Publicly list ANY business that is found to provide services to ice. They stay at Hilton, add Hilton to the list, they eat at Denny's, add Denny's to the list, ect.

I canceled my Hilton Honors account.

Fuck they were SO GOOD for pet friendly travel.

But wherever there was a Hilton Garden Inn there's USUALLY a Hyatt Place too, and they are also pretty reliably pet friendly. Not owned by the same people either, I checked.

Until I discover what they've done wrong as I'm sure its something.
