Needing public transport around Berlin from 18:00 on a Friday until 16:00 on a Sunday, I think I'm happy with my choice of a 48 hour City Tour Card (AB zones). I'd be grateful if anyone would answer some questions I have:
Where can I buy the card at Tegel Airport; I assume bus drivers don't sell this travel pass?
If the card is available at the airport ticket machines, will I still get the map with it and can I select the English map version?
Other than the map, what does the City Tour Card look like; I'm guessing a credit card sized piece of card?
How is the travel card first 'validated' on a bus; do I insert in to a machine or give to the driver?
How is the card used to travel on buses afterwards; show to driver, insert in to machine again?
Thanks in anticipation of your replies!
