Well worth the money. The guide was knowledgeable and I am glad we were able to skip the line thru this tour, because when we entered Eiffel tower around 10:00 am, the wait time in line was 2 hours and when we exited around 12:00 -1:00 pm, the wait time in line was 4 hours. We paid extra to go all the way on the top and the money paid was well worth it because we had two teenager kids with us and we all enjoyed the view of Paris from up top. The guide gave us detailed description on how and why the tower was built and on the top, there is a little closed office type of enclosure with Gustav Eiffel's statue in it, guide pointed us to that. We met some people down below who could not enter the Eiffel tower because the wait was frustrating. I am glad we were able to skip the line.
