Depends on the size. IMHO parties ~10-20 people are the best. If you go bigger, it gets more complicated and anonymous. Didn't like those very much.

For a run-of-the-mill LAN you don't need much. Make sure there's

* enough chairs

* enough tables

* enough drinks, food

* enough power outlets (know where the fuse is)

* possibility to shade the windows

* somewhere to sit and chat without necessarily gaming

* possible sleeping quarters?
