Most of hotels TVs are connected to ethernet cables. Travel always with your own router, disconnect cable from TV and connect to router. You have free internet
I did this for about a year after noticing that the Marriotts I tended to stay at were exposing Ethernet on the new desk/entertainment centers they'd retrofit in the chain. After that year, I started noticing that the ports were dead, usually just unplugged from the wall, but then those started to go out. Eventually, those fancy A/V panels were boarded over with plastic, then eventually fully replaced with plastic insets. But for a short while, it was the promised land, and the moral of the story is that your mileage may vary these days.
Only a small fraction of hotels are wired with Ethernet, and usually it’s the largest hotels in city areas. Even then, I doubt most have Ethernet to the TV.
