I have read that holding places in line is poor form but was wondering if that is always the case. In particular, my wife and I are taking my daughter to the park and the one thing she wants to do is meet Elsa. I am willing to wait in line for 3 hours if that is what she wants. The question is if it is okay for me to hold her place in line while she and my wife go to see other things and bring her into the line at the last moment? More of a line swap since I don't need to meet Else myself.
In one of the discussion on the Frozen meet and greet someone else mentioned that they did that and no one seemed to take issue.
