I just played here yesterday - would highly recommend. The "member for the day" experience is truly that - they treat you incredibly well. Locker room, practice facilities, pool, fitness, etc is all available to you for the day.
The golf course was excellent. Good width, firm/fast fairways. Just two weeks removed from the Dutch Open, it was still in great shape.
All of the heather is currently played as Ground Under Repair in an effort to help facilitate faster growth. I agree with previous posters on other threads who have said this place will only get better as it matures. With that being said, I would not hesitate to return. While there are other courses others have mentioned on here that I would put ahead of Bernadus (RH, De Pan, Kennemer), it would firmly be in the top 5.
