Not all of them are free, mind you, but there are at least two which are.
There are about four hotspots owned by Globequest and Airborne Access, possibly via the overpriced coffee shops operating in the area. But a quick scan via
iwlist scanning(sorry, Windows folks, this is Linux only), revealed two other ESSIDs: SMARTBRO and a generic LINKSYS.
And man, is the Internet access fast. Too bad I'm just about to board now.
So, lesson of the day: check for free WiFi before going GPRS.
Oh, boo hoo, P20 in GPRS charges down the drain.
