Hot Spot connectfion

How do I connect my LAN router to a resort hot spot. I have Ethernet only devices which can't connect to our resort hot spot so I need to find a way to connect my LAN router to the hot spot.
I have seen posts about using an Ethernet wireless adapter but haven't seen any posts that are specific as to what device to use and the exact steps to follow in setting up this connection. Does anyone have any thoughts on this
