Have you tried hooking it up to an Ethernet port in a hotel room like the one that the TV uses?
Some hotel rooms (particularly older business hotels) will have an ethernet port for the guest. These work maybe 50% of the time these days. Sometimes you can find a Ruckus AP in your room at outlet level, and these usually have several ethernet ports on the bottom. These also have a working port around 30% of the time.
So, TL;DR: various ethernet ports in hotel rooms work less than half the time these days.
At that point you're in the 0.1% that the hotel does not really need to worry about. The other >99% will still need to pay for wifi.
