I've lived in Las Vegas for 17 years, and have been to dozens of concerts at various properties. This is by far the worst experience for a concert to date. The staff was rude and unhelpful in providing directions. One staff member yelled at us when we asked why there were no signs telling people where to line up.  There was no order or organization whatsoever!  I'm sure the concert will be fantastic and make up for such horrible service, but I won't be back after this experience!
