If this is going to be a general hotel thread, then I imagine TravelBuzz is the better place for it.

As for Hilton properties, the Hampton Inn Pasco, WA has a pretty full spread - fifty-plus channels including most of the cable favorites (Disney, Cartoon Network, SciFi, etc.).

Best one I ever saw was the Greensboro, North Carolina Super 8. They have over 100 channels - I think everything the local Warner Cable office carries.
