Expected to arrive in Zurich on a Sat morning at 06:10.
My flight to towards Cologne on German Wings will depart at 09:10.
With a 3 hours layover period only, is it doable to visit the city? I'll like to at least see the old town and walk along the river banks since I've never seen the city.
Will there be sufficient time if I board the train from the city to go back to the airport at 08:50? Will shops in the city be open that early in the morning for me to grab a quick bite?
