Getting free access to Intertouch wifi
Nearly all the big international hotel chains (like Hyatt, Marriott, Hilton, Ritz Carlton, Westin, Holiday Inn, Meridien, Sheraton, Westin and Crowne Plaza) provide wifi to their guests via corporate wifi provider Intertouch.
For the convenience of the guests of their hotel partners, Intertouch uses a simple convention for logins.
Username: Last name of guest
Password: Room number
So if you know someone staying at any of their hotel partners, you might be able to score free wifi access.
Unless they change their login convention, that is.
