All that 2d writes above is true I,v used schipol VFR in the past but now prefer to go to hilversum ,Its only a short cab ride to the railway station and about 15 min on the train into amsterdam.
Dont let me put you off Schiphol if that is what you want to do from a flying point of veiw but I have found Hilversum more practical for visiting Amsterdam city center and a lot cheaper.
