True, but we've had opportunities and she still balks.
My girl is pretty astute and is well aware that there's a person in the costume (as I'm sure is the case with most 5/6 yo).
Heck, she even balks when she knows the person in the costume really well! Her Girl Scout leader/PTA vp/bestie's mom was in a Clifford costume at the book fair at school. She loves her and knew it was her but would not go near her when she had the head on!
At the same time, when we ask what her favorite restaurant was...
We thought it might be 50s Prime Time (we went twice and had an amazing time both times)... nope.
or Sanaa (had an amazing and wonderful time)... nope.
or T-Rex (she had so much fun both times here as well, she loves the fish tanks!)... nope.

So you're right, we will see.
