The plugshare site optimized for the car's browser allows you to filter by hotel. Curiously, this feature hasn't made it in the main site and app.
You can access the car's site from any device by entering tesla.plugshare.com Besides checking "Hotels only" you also have to check HPWC for Model S (not sure why it's not selected by default) and CHAdeMO (if you have the adapter). The usual caveats apply. I'm not sure how well flagged hotels are in Europe and public stations near, but not on Hotel property will not show up.
