Are you sure the hotel allows guests to bridge to their routers?

A wireless "bridge" is usually a dedicated wireless connection between the main and secondary routers. Then you'd only be able to use the Ethernet ports on the secondary router.

If you still want to be able to use WiFi clients on the secondary router, that would be "repeater" mode. You'll get reduced speeds because 1/2 of the bandwidth is used to connect to the main router.

Note that you will be exposing all your devices on the hotel's network. Bridging disables NAT on the secondary router. A bridge is basically an extension of the main network.

I don't see bridge or repeater options in the TPLink Archer C80 manual.
