We (Family of 5) will be arriving by train & visiting the Airborne & open air museum in the Arnhem area in a few weeks. We need a place to stay for 1 night! Looks like most B&B places require a min of 2 night stay and many of the motels show no availability or are very expensive for 5 people!
We faced a similar issue 3 years ago when we visited the area for a family reunion. We ended up in two rooms in an Accor hotel nearby: http://www.accorhotels.com/gb/usa/index.shtml
