Hi! We are staying in Amsterdam 15.-20.5. and renting an apartment near the Olympic stadium. Coming by plane. Planning a trip tu Zandvoort by train. My question is about tickets for the local transport. I know that you can walk (almost) everywhere in Amsterdam but ...and I love trams! and anyway we have to get from and to the airport, also the Centraal Station is about 5 km from the apartment. We are planning to take bus 197 from and to the airport. If we want to travel in a cheaper way, I suppose we should buy a OV Chipkaart at the airport for 7,50 EUR and top it with the minimum of 20 EUR. Now I have read about some (Multi) day tickets for tourists, 6 days for 29,50 in our case. I do not understand if we also have to buy a Chipkaart before buying this multi day ticket. And can we buy it already at the airport to be able to use it for the bus 197? Thank you.
