I've got a few questions on the Combi ticket. In the Keukenhof website, the "Combi Ticket Adult Amsterdam" is 28euro, this is the one with the 'pickup point' at Leidseplein (in Amsterdam) right? While if we take the "Combi Ticket Adult Schiphol / Leiden / Haarlem" (23euro) we'll have to get to Schiphol airport on our own, to board the 858 bus right?
We'll be staying in a boathouse near Centraal. Which combi ticket is better/more convenient/faster for us?
I checked the 9292.nl site for the tram ride from Centraal to Leidseplein is 1.20euro, while the train ride from Centraal to Schiphol is 4euro. Is this price with or without the Chipkaart? Don't think we will be taking enough buses/trams for us to get a Chipkaart.
Do we need to book the Combi tickets in advance? Can we buy the Combi ticket on the day we plan to do the day trip? Any price difference if we book online or buy on the spot?
