My family is planning a 7 day trip to the Netherlands next week. We'll using public transit in Amsterdam as well as taking trains to Harlaam and Delft
We had planned to use the TripKey, but it appears that they're still updating their system, so we can't purchase them. It looks lik our other option is the OV Chip-Kaart, but I've found the webiste for the ChipKaart a little confusing.
Can we use these on trains from Amsterdam to Delft and Harlaam as well as Amsterdam transit? And can we purchase them/load them at Schiphol Airport and then use them on the train from the airport the Centraal Station?
