We just got back from a great stay at resort arcen. We stayed in the lux4 bungalow which had a gas fire place and great kitchen. We were very impressed by the accommodation, spacious, good size garden for the kids, great kitchen, eu suite bathrooms - apart from no sauna it had everything.
We have a 4 and 2 year old. There was a lot to do outside for the kids, big play-park, petting zoo etc. The beach was okay - wasn't overly enticing! The indoor swimming pool was not great, well maintained, but no proper swimming for adults, only one slide for the kids. We ate once in the restaurant which was good.
Staff were very friendly, kids enjoyed the mini disco in the evening. Resort was overall very clean.
One thing to note, the resort was 95% Dutch - not surprisingly! This meant all activities are in Dutch, with minimal effort for other languages (e.g german or English). A brochure in English or german would have been good.
All in all we really enjoyed it and will probably be back!
