I'm going to be driving from Aachen to Fritzlar via A4/A40 in early June, and I'm thinking about spending a couple of hours visiting the Cologne cathedral en route. There will be two of us travelling, arriving at about 09h30.
Would the best plan be to use the Park&Ride Weiden West and buy a 4erTicket? If so, I have a few questions that the KVB website seems a little ambiguous about:
Are parking places bookable? (I assume not)
We'd be buying the 4er ticket on the day. How do we make the free parking thing work? I see from streetview that there are ticket machines in the car park.
To use one ticket for 2 people on the train do we just stick the ticket in the validation machine twice each journey?
Also, I assume that given time constraints that the S-Bahn is a better option than the tram.
