Continuing to ask too many questions of you fine people:
Our flight is supposed to arrive at Schiphol at 12:55. Could anyone give me a ballpark figure of how long it would take to go through customs/passport control/baggage claim? We are flying through Reykjavik, if that makes any difference. Iceland is also Schengen, so I'm not sure if that affects customs/passport check at Schiphol at all.
Namely asking, because we want to catch a train to Brussels from Schiphol. How many hours' buffer between arrival and train departure would you recommend?
