I have flown through Amsterdam more than 20 times. A big airport with a lot of walking to be done. Its clean and bathroom facilities are frequent. The central area is full of shops and bars generally overpriced as a beer will run you 6-8 euros. All in all okay however staff and security procedures could be considered intimidating. Most times you go through a security check twice you get questioned one on one about your baggage and your entire day. The only thing I cant understand is their policy with duty free. If you bring a sealed bottled in the duty free vacuum sealed bag with a receipt from another airport they will confiscate it. Originally I thought this was a one time thing but over the years I have lost 3-4 bottles in that airport. I have been to over 100 airports and this is the only airport where this is apparently policy. Besides the duty free stance the high prices and the over the top security procedures I can't complain.
