This depends on several factors, as in what are your interests? gambling, going to a dance-club, sight seeing, dinner, shows, strip-clubs (I have buddies who love doing this for some reason), drugs, etc. Also, there are places where girls over 18 can get into which means the place is infested with young 18 - 21 year olds (horrible experience for me, I felt like an old man being that im in my mid 20s), then there are places that only allow over 21 (which is infested with college kids) then there are the places that I prefer which typically host people in their mid-late 20s. There are so many things to do its crazy. I've been there more than 5x and I still feel like i've barely touched the tip of the iceburg. It also depends if you're going with your lady or buddies. Every experience is different. Every visit is different. But whatever you do, don't do something you can do at home, try something new (one time I went with a group that wanted to play beer pong, at this beer pong place, so we did, the whole time I was thinking, wtf am I doing here, I could be doing this in my garage, waste of a night).
