Bought a groupon and did this on a Sunday night after two of my friends got married in Vegas. This was an excellent activity choice! While most of the spots on our tour didn't have drink specials (same ones as outlines in Traci's post), my favorite was them taking us to the club Body English, where we danced our asses off. While true that we weren't on the bus often or long, we had unlimited drinks on the bus and there were several fun options like margaritas. Our guide/bartender was awesome. This is a great activity for young people in Vegas who want to have a good time with other partiers.
