I arrived at Amsterdam’s Schiphol Airport at about 11.15 am this morning.
I had to spend a little time at Schiphol to figure out how to use my OV-chipkaart* for the train ride down to Rotterdam, but that’s OK. Now I know how to use it in Rotterdam, as well.
*Cannot load money onto it at the ticketing machine with an American credit card! (USA cards do not have PIN numbers). No need to buy a fare ahead of time, but if you travel 1st class, you tap the card once at the station/ platform entrance as usual, and then a second time on the platform next to the train, for the 1st class surcharge.
