Jet is a prime example of the Light Groups nightlife concept. The dance floor is in the middle, with tables surrounding it and bars on either side. It is difficult to get in, even when you do have a table. The light group does this on purpose, a to make the front door seem always busy. The tables are small, just as they are anywhere else. The music is pretty much the same as everywhere else in Las Vegas. The ceiling lights are pretty cool and I hear that there are a couple other rooms besides the main one, although I haven't managed to make it around.
I have been a couple times, I guess I would go if friends wanted to!
