I've been to Niagara Falls (Canadian and American sides) 3 times.  I love that place!  It's amazing and beautiful!  I took my brother and his family (after a weekend visit with relatives in Cleveland) last September, 2014.  We visited the American side (I was the only one with a passport), but it was still exciting to see their AWE and AMAZEMENT.  Especially my nephew, who thought it would be so "lame".  He loved it!  I WANT TO GO BACK!
