Arguably, if you're paying to park at the hotel, or if you're paying for a Hertz rental car (where Hertz pays rent to the hotel), or if you're eating at the restaurant in the hotel, then I think you have a pretty good argument that you "belong" on the shuttle.
But still helpful to know proof is never required...
