Ariel with legs was there a year ago when we had breakfast there. Not what you needed, I know.
I just wanted to say that we saw her in the MK last WEEK (I think it was on 5/13) as you enter Adventureland from Main Street, USA. (She might have been there with Prince Erik, too, but we just saw her from the main walkway.) She also had her "human legs" then. Just a thought for you in case she is not in Norway when you are eating.
Have a fun trip!
