I love New York and London, but my favorite city I have visited so far has to be Edinburgh, Scotland. I have been to the Fringe Festival twice and it is just a magical place. I highly encourage everone to go.
The most beautiful spot I've seen so far, though, has to be where they filmed The Mission with Robert de Niro - Foz de Iguazu at the borders of Brazil, Argentina, and Paraguay. It's gorgeous! Anyone who can't think of a honeymoon spot, go there! Over 300 waterfalls all larger than Niagara and the most species of butterflies in the world.
