Hi Chaim, been there done that, when i went and i went to quite a few back in the day, they were not good for me but at that time i wasn’t a very sociable person so i dont know if it works for others or not, what i did see was a lot of fraternization experienced singles who knew each other and spent time hanging out together.
Things i did like at these events, the food, entertainment, the food, some of the lectures were very good some were too lectury, the food, some of the social activities games and such, the food etc.
