um i seriously dont know, are you connected wirelessly with the xbox? if not then maybe you could use the network cable supplied (which you can purchase if you didnt bring it) and connect to your laptop (i guess that is what you brought with you and that it is wirelss access you are getting in the hotel) and share the internet access (i cant remember how to do this as it has been ages when i used to use it with my slimline PS2), you may have to disable the firewall depending which one you have (if you have Zone Alarm you'll have no choice but to turn it off).
