Ariel can be found in her human form at Magic Kingdom in Adventureland. Ariel's Grotto, where you could meet her in mermaid form in Fantasyland, was taken away in early August 2010. I've also met her at 'Akershus' in fake Norway, and at 'Cinderella's Royal Table' at the Magic Kingdom.
Ariel is sometimes paired with Eric in Adventureland, if you're lucky.
