While the actual Eiffel Tower in Paris is 10 times better this is not bad. It gives you a completely different view of the strip and the beautiful mountains surrounding Las Vegas. I was not able to go up at night this trip so I cannot comment on the evening show but during the day offered gorgeous views of the strip and mountains.
I think it a little overpriced but I learned later in the trip that there are booklets around Vegas that give you buy one get on free tickets. It is definitely a site to checkout.
