Stayed many times. The Courtyard Airport is way out past the airport, don't even think about it unless you're flying out the next am, just too far out of town. But a nice hotel right on a park.

Stayed at the Marriott AMS many times and love the location. Lots of bars, clubs, restaurants, parks withing 2-3 blocks. Nice hotel, nice health club. Safe area. Make sure to do "Boom Town Chicago" comedy troupe across the road, especially the late show on Friday, a blast!! Couple of hot nite clubs around the corner, Jimmy Wu's is supposed to be one of the best, had a great time there. Enjoy.
