On Saturday I will be leaving for vegas for 5 days. I have never been there, but my girlfriend has many many many times. She just turned 21 last week and she is looking forward to finally enjoying all of las vegas for once. We will be staying at the Rio. Don't have nothing really planned as of yet, just drinking and gambling. I've been perfecting my blackjack skills. So is there anything that has to be a "must see" in anyone's opinion in vegas? We know some people that live there, so that plus gambling, drinking, and soaking in some sun is all we got so far. So if anyone knows of any shows or places that are a must, i would love to hear about them.
