If you attended a running festival, you are clearly not the type to fall off a yacht while being drunk.
We were also there in May a few years ago. An English drunk individual took off his indispensables at the hotel's pool so that the lifeguard, a middle aged woman, had to caution him to put them back on, accompanied by the laughter of his drinking companions. It at Occidental Puerto Banús, so not at a cheap hotel.
