Im sorry to say, but you cant do this. I am guessing that the internet u need u have to pay for, and you pay for it by logging on with your laptop, and paying on the internet, as the hotel will not allow you to go to any pages other then the payment page. Basically when you pay, the internet router at the hotel allows you computers IP address to access the internet. Here is something to try tho, write down the IP address of your Xbox, go ask the people at the front desk if they can add that IP address to there allowed list. Hope I helped!
