Ok, it's been a while since I went here, I admit it. But I just fail to see the attraction of the place. Sure, it's big, there's lots of grass and some water. There is a "canteen" with a cement patio where the kids dance at night, but it just doesn't seem like there's much else to do or see here. The last time I was at their beach it was crowded and filthy, I wouldn't bother with that again.
However, if you are looking for a unique little weekend trip, they do have cabins that they rent out (I believe they call them "tents" even though they are permanent structures) - it's camping with a suburban twist I guess.
