We've stayed at Duinrell twice, and we just can't complain. On arrival it's a bit tricky as your not sure where to park, as you are merging with all the theme and water park traffic. The park itself is great for families of all ages. We stayed with eurocamp and the caravan was clean and enough space for 4. The highlights for is are: wassannar - a short walk or drive (use the underground car park) with a good supermarket, shops, 3 italian restaurants, and not forgetting the ice cream shop - you can't miss it! The theme park - big enough to walk around for half a day, and not busy so you can get on all the rides. Leiden - 1 hour away, university town with canals and historic buildings.
