Looking for Dutch "hosts"

[servicepub (RIP)]

My son and a friend are going on the Dutch parachute course in April/May 2006. They are looking for a place to stay the night of 28 April and the night of 7 May (dates may change by a day).
This is a course run by a private firm for the Royal Netherlands Army and is open to anyone who is prepared to pay the price. As my son is bankrolling this trip on his own he hopes to save the cost of two hotel nights.
I realise that the Netherlands is a large country and, if interest is shown by anyone, I will find out exactly where the course is in case it is too far to accept your hospitality.
In return, any MLU'ers visiting Ottawa will always have a bed, breakfast and beer at my place (whether you can help my son or not).
