I have about a 6 hour layover at FRA en route to VCE in early May (Sunday arrival). Is there any way to amuse myself (or more importantly, my travel partner) for that time? We're flying US Air. We don't have club access. He was wondering if it's possible to catch a cab or something to just get out of the airport and do a little sightseeing. We probably won't have much for carryon so schlepping luggage around won't be much of a problem.
