I know it isnt feasable for most locations, but Wii 'kiosks' should look like those 'cubicles' to present home theatre systems. A nice big TV, a sofa and some nice space inbetween.
Having just a standard kiosks with some Wiimotes tied to it is quite a contradiction to the ads, where players are in some open white space and have room to move and really use the Wiimotes as they are supposed to be.
