She's mistaken. Kings Island's (and Kings Dominion's) Eiffel Tower is only 1/3 scale. The US one that's half scale is in Las Vegas at Paris casino. Perhaps they did some magic to make both it and the one in Paris duplicates adding up to what was once the full scale Eiffel geegaw in Paris, France!
If I'm not mistaken, isn't there also a restaraunt on the low platform of the one in Vegas along with the one in Paris.
Also, was the one at the Paris Casino built by Intamin?
lol i kno its a tottaly diffrent one but i did not know there was one in kings domimion too...
