Niagara Falls/Toronto.
After 34 years of marriage, we finally went on our honeymoon (only kidding). Niagara Falls is amazing. After much research, we decided to stay on the Canadian side. There are many attractions, some more touristy than others. A lot of walking, so bring appropriate shoes. Toronto was fantastic, again a lot of walking. When the venues you want to visit are too far to walk, the mass transit system is easy, quick and clean.
