Background info - I will be visiting the Netherlands for about a month starting early July. I will be traveling with my wife and four kids, ages 8 - 14. We will be staying in 's-Hertogenbosch. In my planning, transport has consistently been my main financial constraint. Even though the 8 and 10 year olds can travel on discounted Railrunner passes, round-trip tickets for the other four people in our family from Den Bosch to different day trip locations can add up quickly. For this reason, I am trying to use the Discover Holland day trips as much as possible, which, if I understand correctly, provide round trip train tickets from anywhere in the Netherlands to certain locations.
I have appreciated the very thorough advice given by locals in this forum. If you see any places or regions that I'm missing that you highly recommend, please let me know, as I am looking to start finalizing our itinerary. Our main objective is to just have an enjoyable time, discovering the country. I guess we prefer less crowded, picturesque places. Modern architecture is not a big priority, so I plan to skip Rotterdam. We will probably buy the Museumkaart and go to museums in whatever town we end up visiting.
Den Bosch - we will obviously spend quite a bit of time discovering the city and the surrounding region
Amsterdam - we will visit the major tourist sites
Haarlem - Corrie Ten Boom house, National Park Zuid Kennemerland
National Park Hoge Veluwe
Nijmegen
Utrecht - including Kasteel Den Haar
Maastricht - I am particularly interested in the caves
Arnhem - I would like to visit one of the outdoor museums. I picked this one since it is closer than Enkhuizen
Den Haag - will probably visit Madurodam since we will use the Discover Holland passes to get here, the Humanity House also looks very interesting
Kinderdijk - we will also try to visit Dordrecht on this day
Efteling
National Park Veluwezoom - hoping to catch the heather bloom before we depart
Specific Questions:
1. Is it wrong to skip Delft?
2. There is a Discover Holland day trip to Giethoorn, but the hordes of tour groups sort of scared me off. Is it really worth going there?
3. I am interested in the Hanseatic cities, but transportation is my main issue. A car seems like it would be ideal, train seems expensive and somewhat limiting since we're trying to just do day trips. When I looked into it, it seemed like renting a car was quite expensive when it needs to seat 6.
4. There is also a Discover Holland day trip to Groningen that is fairly inexpensive. Is that worth it?
