It's not particularly special, but we really enjoyed it when we went with our then-two-year-old. Other than Belle (at ETWB), it was her first character-greeting experience and both Elsa and Anna did a great job with her. We had FP+ and nobody was behind us (I think maybe it was some kind of character shift change?) so she didn't feel rushed. Elsa greets first and then Anna, and the best part was when my daughter asked Elsa, "Can I go see Anna yet?" Ha!
