This is a fun place to go and get a view of the city! A half scale of the real Eiffel, the workers are friendly and even gave us an iPad to use as a tour guide while we walked around. We were able to walk around at the observatory deck up top and point out the different places that we wanted to visit that day.
While it's fun to see the Strip lit up at night, you can see the city by day and it's less crowded. So it isn't that I recommend one over the other, it's more of a personal preference thing.
