I did all of the touristy things in Vegas, but by far the Eiffel Tower experience was one of the top five best touristy things to do.
You can literally see the entire strip from the top. You also get a really neat view of the balagio fountains which is probably a lot more neat at night, but even during the day I was impressed.
The elevator gentleman we had was also hilarious! lol I would want to just take an elevator ride all day to talk to him. He really makes the experience special.
The only bad part about this was the lady that tried to sell my boyfriend and I our photos we took...she was quite pushy and all I asked was for her to add the date to our photo...it wasn't asking much...
