With work and family, they really don't have the time for trolling swingers' forums or trying to organize dates with strangers.
Imagine a week-long festival of beach culture on the best beach in the Canary Islands: Beach volleyball, chilled-out music, cocktails, fire twirling, sand sculptures, a big market along the Meloneras promenade, etc.
This means that there is plenty of room for everyone on the sand, nude or clothed.
