This place is a great option for discount tickets to shows in Vegas. Most show tickets are for day of, they do have a few next day tickets available now. Friendly staff for the most part. Be prepared for long lines and go early. When it is busy the line starts out on the sidewalk.
However, check for specials on individual show websites. Occasionally seasonal specials can make tickets cheaper. This place is a good deal, just make sure to shop around first to make sure you are getting the best deal.
