When I have a visitor with a laptop, I just get their MAC address and add it to the list, it takes a minute at best.
More advanced firewalls/routers will allow you to setup a seperate vlan for your wireless visitors, then all you need to do is provide them with the password and they will be able to connect. Much easier, and more secure than MAC address filtering. Albeit, more costly.
