I have signed up for a three hour private tour with a driver. It is a minimum of 3 hours so I use it or loose it but I don't want it to be any longer.
I am thinking of either Hague or Zaanse Schans ?
Which one do you vote for?

Thank you

Neither, a waste of the car, since both can be reached by public transport and give your driver nothing to do while you visit. Den Haag certainly needs longer than the time you would get from a three hour tour, and would be a pain in a car. Zaanse Schans is a tourist trap, but I guess you could do a quick trip there and then the other tourist trap of Volendam in your 3 hours.
What interests you? What are you hoping to see/do in that time?
Why sign up for a tour if you have no idea what you want to see in that time?

Do a tour to locations you could only reach by bus otherwise, like the village of De Rijp (an 18th century gem)
