Found a site which may be of interest to funsters called www.citycamp.com. It lists campervansites near Dutch cities. Per 1 july 2012 one will be opened in Amsterdam, costs 10 euro's plus 10 euro's p.p.p.d. including everything. It will be guarded 24 hrs. Greetings, Hans. Sorry, this www.amsterdamcitycamp.nl is the right one.
