I love The Light! It's my new favorite Vegas club! There is always access to the main dance floor.
Pros:
1) HUGE, so there's plenty of room
2) Great ventilation
3) Cirque du Soleil performers hanging from the ceilings
4) Sold line up of DJs spinning every weekend
5) Consistent access to the dance floor, while at other clubs, they block off the dance floor.
6) Entire wall full of LED monitors
Cons:
1) Dance floor is small, but larger than many of the other clubs in Vegas
2) Hella crowded around the bar closest to the entrance, so it's difficult to get to the other side
