I know this has been asked before, but here goes nothing. We are taking my son (who just turned 21), and his friend to Vegas. We will be on the strip for three nights, and then five downtown. My question is, where can the boys go downtown where there is a younger crowd, as in nightclub or bar? We will be there from a Thursday to Tuesday, so we will be downtown during the weekend. I know they could go to the strip, but I would like them to enjoy downtown as much as we do. Thanks in advance.
