We had a chalet for 8 persons. As we are all couples, the rooms are not ideal as you have a room for 3 and a room for 1 (very small!), but we managed to get all controled. The beds are terrible. These are no mattresses but just a foam part so you can forget a good night sleep.
The location is ideal for divers as you are very close to dive locations in Zeeland. Also the centre of Wemeldinge is not far away. When you arrive late your first day, you can inform the reception and they manage that you get your key although the reception desk is closed.
