Public transportation in Amsterdam
Within Amsterdam, the tram 26 connects the Central Railway Station with the conference venue Pakhuis de Zwijger (Kattenburgerstraat, just 2 stops away) and with the Lloyd Hotel (Rietlandpark, 3 stops).
Local public transport is managed by GVB. It's possible to buy single tickets, but a multi-day pass (OV-chipkaart) may be convenient if you plan to use public transport often. Or you might do as the locals, and rent a bicycle.
