I can't imagine doing it in the daytime. With huge pupils, it would be too bright.
My best time was in a group of about 15 at a house party, great music in a dance room with black light and a disco ball; quite dark... and at times, completely dark. You stayed and danced as long as you wanted, or you wandered off to a room with music videos playing, or wandered off into the dark to cuddle with the others, or to just catch a smoke outside. A hot tub and pool right outside kept my wifey happy, and pretty much everybody was mixing and mingling with each other all evening.
It helps if everybody is not the jealous type, because E brings out a lot of emotions, hugging, and this particular night was in the heat of summer, so there were not a lot of clothes on at the beginning, and a lot less was worn as things heated up.
Now the kicker: every single person at this (including me) was over 50 years old, with the exception of one girl's younger sister who was about 42 then. While this super memorable night was about ten years ago, the whole gang who live around where this was (Southern California) still do much the same thing at each other's houses about every other month. Like about half the people, I live thousands of miles away from this scene, and fly in mostly to attend these parties 2 or 3 times a year.
At the end of most of these, the hostess asks "So, was this the best ever, or what?" I always agree.
