I'm in Amsterdam for a few days and would like to know what would be the best option to travel in and around Amsterdam( Zaanse Schans and Haarlem)?
1. Is the GVB ticket valid outside Amsterdam?
2. If not I guess the OV is the only option, but should I pay the 7.5Euro for the card or should I just buy normal tickets? (As I said, i want to move around the city and 2 go in the 2 locations mentioned above)
