don't bother paying full price because you won't be up there for too long. the night view is beautiful but of course they have safety mechanism in place such as metal fence over the eiffel tower so that you don't throw things over. the 2 for 1 coupon can be found in various books. i got mine from signing up at bally's for the total rewards membership casino card(free). i spent about $30 for 4 people to go up at night for almost half hr. then it got too cold (in december)!! remember to bring a scarf or a light jacket/hat to keep you warm if you want to hang out longer. the elevator ride up /down was pretty cool and scary since its see through! perfect for those who have not been to eiffel tower and want to get a feel.. or even for those who have been!
