As part of an Interrail holiday, we stayed at Kaag Resort for 5 nights as a family of five. The apartment was really great, especially the large living area with integrated kitchen and nice big dining table. There was also a view directly onto the harbour. Warmond is also a very nice place with a great bathing area, park and playground. We rented a boat on the last day and enjoyed the view. On another evening, we went bowling in an equally fantastic bowling centre nearby. On two days we went to Amsterdam. On paper, it looked a bit complicated at first (bus to Leiden Centraal and from there with the many trains to Amsterdam), but in reality it was no problem at all.
