    Probably there is a "transparent proxy" (google for it) which either
    forward your requests to internet or shows hotel's web site
    there you can pay. After this the web site reports to the proxy that
    from now on your requests should be forwarded to internet.

    Alternatively, there is just a dynamic firewall/nat (without proxy)
