Wireless Connection Instructions

I was wondering if anyone has a list of how to connect to a free wireless network like a hotel guest internet. I work at a hotel and we get so many questions and when I direct them to the customer support sometimes the guest has to wait for a long time before they get help. So basically what I am looking for is a list of how to setup your laptop to access the network using win XP, vista or Mac. I know is easy but sometimes people get conflicts with their VPN and domains and sometimes we get people that don't even know how to access their windows wireless connection setup screen so if anyone has any recommendations I would really appreciated.

Thanks in advance
