With the Sahara now gone, there really aren't many of the original casinos from the 1960s and 1970s left on the strip. Unfortunately, Circus Circus really hasn't upgraded, well, anything, since then. When the biggest food attraction is a Krispy Kreme outlet, you know that there is trouble. The circus acts are free, and interesting for a few minutes, and may hold your childrens' attention. The Adventure Dome, and its games and rides, is also good for children. But the point is, if you don't have kids, there is really no reason to be here
