Could be worse. When we flew into Sanford on PanAm back in 2001, my poor dd had her Corduroy bear all set in her bag, ready to be 'xrayed'. But, she was told that no stuffed toys were allowed in carry-on bags!!! The bad part was that I had called PanAm several times before we flew out since they don't allow a lot of carry-on stuff.....a handbag type bag, that's it. I was told it would be no problem and it wasn't for the flight down. She has never flown without her bear and since it was right after 9/11 she was very nervous about flying to begin with. But, PanAm in Sanford wouldn't allow that bear on with her...no wanding, no xraying...nothing. He had to go in the checked bag. Poor kid sobbed for an hour. And they wanded her to boot!!!
I would suggest you make a game of it with your dd....tell her that her bear is going on a ride, just like she will be at WDW, he just gets to go sooner. She can stand there and watch him come through...who sees him first kind of thing.
