A good time! Basically, it starts by meeting the group, making up a fake name and putting a sticker on to let people know if you are single, etc, and playing drinking games to break the ice. There was a drink special for our group I think at bar one (though it's all fuzzy now). There was also some food at stop one, but I ate before (and suggest you do as well as there wasn't very much). Anyways, we proceeded to hop around while making new friends and ended up at Chataeu which was AWESOME by the way! You do get in first, but one of the clubs (Koi) was empty when we got in. It got packed about 30 mins later though and it was a hoot (and we scored a nice seat which we made sure we kept). Our group was about 40 people so it was managable and very friendly people. The guides were amped and fun, and you can get some good drink specials (armband type deals). I would recommend and do again.
