Choose a locker of the size you like, they have big ones to fit 2 normal size luggages. Pay 7 Euros, lock the door of the locker and the ticket will come out. Be sure to keep the ticket, the bar code in the ticket upon scanning to the light will open the locker. Purchase a train ticket at the amsterdam terminal through the ticketing counter. Avoid the booth ticketing, you might a get wrong ticket and changing it to the ticketing counter might be a little bit disappointing. They will replace your ticket but with facial attitude. As an excited, tired passenger and trying to do it fast in the ticketing booth is actually a big mistake. Tourists make mistakes and I am sure these people knew it. A bad facial attitude make it worst. Train schedule is all day, night and early morning. We left the city to the airport at 3:30 AM and took us only 15 minutes.
