hi! we were 2 years ago in Venus resort, for a party, and check the atmosphere.
The facilities are nice, but we found it too "ordinary/without style". Mostly germans, (we live in germany, but we are mixed from spain).
I do not know how to "give a rating" to it.. the only worst place that i have been is in Cap D'agde.. if you can get what I mean.
However, if you are looking for explicit sex at any time of the day without any limitations... Venus or Le mirage are your place.
We would recommend to go to a "nudist resort" and then go for a party (friday, saturday or sunday) at one of these places... or a swinger club.
we were also in several swinger clubs... but that is another story.
