My wife did a lot of spa days being that kind of refined lady. And the hot-air balloon thing before it floated off. Despite putting 'lost wife' posters on all the nearby lamposts, that was the last time I saw her. I even offered a reward. Anyway.
OK, I can maybe see the activity ones, but the getting stupidly drunk, not so. I passed one the other week, where the groom-to-be was just wearing a nappy and I'm pretty sure he might have used it. Yesterday, a hen-do that would have sent Genghis Khan diving into a ditch and playing dead till they'd gone. I was quite impressed that someone so obvious drunk could still walk in heels that high, but in retrospect, I think she was only upright because someone had tied a significant number of helium balloons to her.
