all I get on my apple tv is computer and settings logo

That occurs when the ATV is on a network but can't reach the larger Internet. When you get onto the hotel network with a computer, do you have to go through a sign-in page? If so, that's the problem. There is no way I know of to get around that.

Apple TV has no browser, as such there is no way to connect to the network. You will need to contact the provider or someone at the hotel to see about another way of connecting Apple TV.
