Boingo WiFi, Northwest and Marriott

Boingo WiFi is a partnership that gives you unlimited access to many WiFi networks for $20 / month. I started using Boingo for access at MSP and DTW. Now this week I have noticed that iBahn/STSN (Marriott) is now a Boingo Partner, so I can use my Boingo at Marriott, pretty sweet, rather than the $10 / day!
