There's this one area on the second floor of Amsterdam's Schiphol airport which has these long lounge-chair like things. Quite comfortable. I dozed off fo a couple of hours. The flight got in early at 5:15 am.
Right next door was the chapel ... or rather, the "Meditation area" space for personal prayer. Brochure for the Airport Chaplaincy service (11:00 am Church service on Sunday) And a sign saying that the "Moslem ritual washing area" is in the washrooms nearby.
Think about it -- who do you think will be prayng here more often? Christians? Or Muslims? Well, actually, I doubt that the devout need the chapel to find the qibla for salat.
