I've been to the Stratosphere Tower several times since it opened back in the 90's and it's just the same thing over and over and the lines can get pretty long. The observation deck is a must see if you haven't been there, it has 360 views of La's Vegas and you can give your visitors a quick tour of La's Vegas without driving around all day! LIL
They do have some rides on the top of the Tower but don't look too thrilling and the sky jump is lame since you're attached to a bungee cord when jumping off the Stratosphere Tower. This Tower has become a staple of the Vegas skyline and tourist attraction but the observation deck is worth looking and it can get pretty cold and windy. .
