And proving that you're not responsible could be stressful, time-consuming, and expensive.

If you want to keep random folks from easy jumping onto your network, WEP will do fine. It won't keep determined folks out, but I wouldn't be surprised if it kept the OP's borrowers off his network. - geoff

My router and my cable modem blink on and off at about 2Hz. YMMV

If someone wants to crack my WEP in 2 weeks so be it. I'll still detect them because I only allow 2 192.168.1.x IPs out through my firewall. I see one of the 2 IPs is being used and my WEP key gets changed.

How many opportunities are there between my router and the destination site to sniff my communications? How many Windows and IE users have keystroke loggers downloaded to their systems everyday due to stealth malware? Cable networks were WAY less secure than my home wireless network, don't know if they still are. I'll take my chances with my current setup.
