In Cinderella, Snow White, and Sleeping Beauty, but the princes are also practically faceless and clones of each other in those movies, too. Can't think of others off the top of my head.
Even though - in The Little Mermaid - Eric and Ariel fall in love at first sight, there's still half a movie of them romancing each other (or, actually, Ariel trying to romance Eric and him falling in love with her even though he doesn't want to). Beauty and the Beast is also an exception, like Bromance said. Mulan and Pocahontas are exceptions, too, I think. Even Hercules has a better love story! Maybe. If the frogs were humans instead of frogs when they danced and almost kissed and said mushy stuff, I might feel differently.
