You must check it out if you head to Vegas. During the day it's just a roof with holes to let the sun in, but when the sun goes down, it is transformed into a giant tv screen spanning 2 blocks. The site says 6pm, but they didn't turn the lights and music until about 7:30pm. The last show is midnight.
The music stays the same, but the graphics and presentation change. Last year's theme was more 70's while this year's was themed more like the 80s.
The activities to do around here are very touristy, but you can see a lot of the older casinos. After all, this is the original Vegas Strip. Along with the casinos, they have the Fremont ziplines and the Neon Sign museum. They also have a stage where some bands were putting on FREE concerts.
