I would l’amour to be Ariel because she had the courage to give up her comfortable life to find l’amour and even when it seemed hopeless she didn't give up.
While it would be cool to be a mermaid, I think jasmin is a better option. She's got the Genie, the carpet, three awesome (and most likely trained) animals, she lives in a warm climate, has an awesome wardrobe, and her guy is Aladdin. Who wouldn't want to be jasmin for that alone
In reality, however, I'm like Cendrillon before she married into royalty...I doubt that counts for anything though
