Rest and enchantment in Bosrijk holiday park. The Efteling is a short walk away, and entry to the park is included in the price. And I don't know if it's because the Sandman visits - but you can also sleep really well there! Oh yes, and it's a bonus that you can enter the park 30 minutes before people who aren't staying at the holiday park. :)
While all the day visitors are waiting at the gate for the park to open, you can start enjoying a few of the attractions, or be first in the queue.
