I stayed in Beach Hotel (Van Oranje complex) for 3 days for a seminar at ESTEC. Something fantastic. Breakfast buffet was marvellous, offering everything you want without any limit!
Rooms are beautiful and clean, with all comfort you need. You also have the view to the see that is, at night, very relaxing. In front of the hotel there's perhaps the only bar on the beach.
The relaxing centre is full of every comfort you need: sub-tropical wave-pool
Two saunas, Whirlpool, Turkish bath, Mist garden...
