I been here twice to the LV Eiffel Tower. From my experiences, there are a few scenarios.
1) The I never been up there before: Go, enjoy the view. It is cool for the first time
2) I been up there before: Do not go. Wait for friends downstairs and gamble in the air conditioning. It is like hell up there and heaven in the casino unless you are losing.
3) I been, but I am with a significant other who wants to go: Tough luck buddy suck it up or make up a phony excuse.
