Not generally. She is not on FP+ though, so it is standby only. Usually if you show up about 10-15 minutes before she is scheduled to appear (you can get her exact times in the
MDE app or on the times guide or from the CM placed at her greeting spot) you will easily be able to see her. Her least busy times will be in the morning, though I think early evening (dinner time) isn't too bad either. The longest lines will be in the 12noon-3pm range. I manage to see her pretty much every time we go (usually every weekend) since my daughter adores her.
