Yes, we sent to Sunparks De Haan when DS1 was little. It's an easy drive from Calais and it's a nice, clean park. We had a cottage with 2 rooms upstairs and an open plan downstairs. Nice indoor water park with waves and slides, etc. It was a bit too much for our DS, who was only 2 at the time, but would be fun for older kids. Beach is a bit of walk and was breezy! Close enough to Bruges for a day trip.
