Before reading, know that I have been spoiled by awesome rides and coasters in other places like Magic Mountain in Valencia, CA.
I went on all 3 rides here. The only one really worth it is the Big Shot at the tip of the tower. There is no need to go on any of the other rides except maybe the one that makes you feel like you're going to fall off the tracks. The green spinning one doesn't need to exist.
I did the rides during the day but I would have preferred doing them at night because the view of the main Vegas strip would have been more awesome. During the day the view all around the tower is pretty nice but if I had to choose, I'd choose nighttime.
Since I stayed in the hotel for a night we got a lower price for tower entrance and the rides.
