I'm a sucker for a good light show. I really wouldn't recommend coming down to Fremont Street unless the lights are on (except for you hard-core gamblers, have at it!). I'm a penny-slot kind of girl, but I killed it. Maybe I just happened to have lady luck smiling on me that day, but I wouldn't be surprised if the games were a touch looser down here. They gotta draw the crowd somehow!
The rooftop shows are pretty cool (I made my group come down for the Queen one). The people watching is better though, so if you're prepared for that kind of entertainment, you'll have a good time.
