We stayed there in 2008 for a week ( very handy for Rhine & Moselle) and also a one nighter in 2009 on our way to Italy. It's an excellent site with a decent restaurant. As has been said - it's not far off the motorway and there's a service station just by the slip-road. A bank with cash machine in the village you'll go through on the way there (just off the direct route) and a shop. The site owners are very helpful and there are at least three overnight areas - you can usually park up and leave everything hitched up. There's also a small shop on site which sells bread, etc. It's very popular with the Dutch.
