lol, how is that not a thing with kids everywhere? And the slides are usually designed with that in mind and if no one get's stuck and with proper timing, it's not really dangerous.
But there is like a science to it. With big trunks you have to pull them down, almost to your knees, otherwise they will still catch water and slow you down. Something like Speedos you can just tuck in between your ass cheeks, but they might still slow you down if you shift balance towards your back, so for max speed you still need to pull them down.
Guilty. It's definitely not a hard con and I just put it there because you'll basically only see old people (60+), at least in my experience. They make up like 80% of nudists, which kind of stands out. But it's great at the water park because they'll all be sticking to the saunas and mineral baths and usually don't bother with slides or the wave pool.
Went to the water park with some friends for my 15th birthday but didn't realise it was nudists night. We decided to stay anyway and I only went back on nudist nights after that. It's great.
Pro:
Most people will leave, so no lines on the slides/rides and you can use all the floaty toys.
No need to pull down pants to go faster on the slides
Not quite sure what you're taking about. The number of vacation days has been increasing over the last few decades while work hours have gone down. At least in most developed countries. Hell, even having the weekend off has only been around for a hundred years or so. I sure as shit wouldn't want to go back to work on some medieval farm ...
