It is recommended to buy the Airport-City-Day-ticket from the ticket machines. It can be used for as many trips as you like: single ticket (Euro 12,40), group ticket incl. up to 5 passengers ( Euro 23,20), automatically validated from moment of purchase until next day 6am on the entire MVV network.
Parking is possible (though limited) against a fee in the surrounding streets. Given the limited public parking options the use of public transport is highly recommended.
