do you know there is a nonrev assistance center at AMS?
"The new center is on level two of Schiphol’s Terminal 2. The center, which is past passport control, will be open seven days per week, from 9 a.m. to 5:30 p.m. During the winter the center will be open until the last flight has departed. To reach the center, visitors may take the escalator near the Holland Casino on the first floor between Piers E and F."
