One of my FAVORITE things to do at WDW or DL is to watch the lines of little people having their photos taken with characters. DH and I are lucky enough to visit WDW and DL often so our holidays no longer in "commando" mode.
I agree, it IS uncomfortable when you watch a parent forcing a frightened child to have his/her photo taken. Seems a little selfish to me.
Luckily, they are rare and I'm back to my ear to ear grin watching the joy on a little girl's face when she meets Belle, or Cindy, or Ms. White. Now THAT's Disney magic!
