Husband, I and two sons (9 and 8) would like to take the car to the Netherlands this summer, probably taking the boat from Harwich to Hoek. Over the course of a week we'd like to go to Amsterdam (and probably Den Haag), some pottering round the countryside and probably Efteling. At at loss of where to stay - Duinrell initially looked good - kids would love the water park - however having read some reviews on trip advisor I don't think it is for us (we prefer peaceful cottages to busy holiday parks but can tolerate the latter if the kids like it).
I'd appreciate advice on which broad parts of the Netherlands are best to stay in, bearing in mind it will be a base for travelling round. A small pretty town with some local facilities would be ideal. I really don't know where to start. Alternatively we could consider splitting the week between Amsterdam and Efteling (staying at Efteling itself). But if we did this I am really not sure what we'd do with the car in Amsterdam as it doesn't seem very car friendly. Perhaps we'd stay in the suburbs and train it in?
