Beirut Movenpick EXEC Floor
Exec floor has free wifi, also free in exec lounge.
All other floors, etc, pay.
Slight aside: Fly MD, thanks re Basel, (close to home for you), tried leaning out of window to catch the signal, but never worked.
Marriott near Zurich Airport, was not free when I was last there, but picked up "free" wirless signal, good enough to check E Mails.
Thanks to all contributors: idea: can we put Hotel name in headline, to assist searchers serching.
