We have it. Each cabin is hard wired with an eithernet connection and there is a Wi-fi router in the middle one so it covers both neigboring cabins with plenty of strength. Most people seem to use the wi-fi now. When we first opened fewer people had wi-fi enabled laptops so the hard wire was more popular.
I have it set up so the is a DMZ (geek speak for safety zone) between where the guests access the network and where my own computers access the network. (requires 3 routers total ... a moddest cost for the peace of mind.).
How did you do that? I am not altogether certain we are safe from bored teens...

Here is the basic diagram
If you need wireless for your own use then have Router #2 be a wireless router and lock it down with Wep Encryption to make it secure.
Each router should be set up so it only reveals its own MAC address
(Most come set up this way by default) This way anyone connected to Router 3 can't see anything that is connected to Router 2.
