Just because she had never been outside her tower until Flynn came around then she finally got to experience the world and I suppose that if you hadn't before it would be quite adventure

As we are talking about the original movies and not other appearances, Rapunzel definitely got the most adventure. The first 3 got NONE, Ariel barely exited the human world, Belle enterin an enchanted castle is barely an adventure, Jasmine flew a magic carpet and went through th town with Aladdin in the beginning, Pocahontas stopped a war but that is not an adventure, Mulan definitely had an adventure with the war, Tiana went through the ball you to reverse a curse, while Rapunzel escaped knights, explored her town, and went to a bar. She definitely had the most adventure

Ariel's entire life after being turned into a human by Ursula, by experiencing new things in the human world and taking part in the battle in the underwater world.

Because she went into a completely different world. If it was me and I went into another world I would be so excited and having such a great adventure.

her then Mulan,Tiana,and Merida....then maybe Ariel and Belle....

She wanted to get away from her life in the village.

Oh, definitely!

To be honest, all of them had a great adventure. But Ariel's dream was to go on land, and she took the challenge by giving up her voice. She only had three days to make Eric fall in love with her, and she knew the consequences. She also discovered many things that she never knew about. If I were Ariel, I'd call that an adventure of a life-time.
