I will be in Amsterdam in mid April and want to purchase a 4 day unlimited pass (I think that covers buses as well?). I went to the gvb.nl website and it looked like they might be discontinuing paper tickets as of mid March? Does anyone know anything about this? Also, I wasn't sure if that pass will get me from Amsterdam central to Keukenhof Gardens (looks like a bus to Schiphol then a separate bus to Leiden?
Thanks
