@Amy-and-Stephen0 Netflix is cheap: why not just leave an account logged in for your guests? We purchased the larger Netflix package (it'll allow 4 devices access at the same time, which covers our Airbnb and cottage as well as our own use) and it's still only $17 CAD a month. Then no worries about them not being able to log in, or leaving themselves logged in and getting upset because someone else used their account, etc. The maddest guest I've ever had was annoyed because they left their account logged in (they did) then said someone at our Airbnb had been using their account (they didn't... we didn't have any guests during that period). Just better off not going there, in my experience.
On the other side of the coin... we don't have cable or local stations, and that's caused no end of trouble. We specify it in our listing, including under things the guest needs to acknowledge before booking, and people still don't get it. We tried offering free to air stations so people could watch sports and local news, but they were unhappy about that too because there weren't enough stations, or sometimes the stations briefly dropped out. It seems that TV is a divisive subject!
If you're determined not to offer any streaming, I would just be straightforward about it. There's nothing wrong with saying "We offer smart TVs with cable and satellite stations. You are also welcome to sign in with your own account to watch Netflix or other streaming services." Just be warned, please probably still won't read it and will still bring their own expectations.
