I'm excited to see the new queue in person, but I do have a couple of concerns. I know people are going to want to stop and look at stuff (I sure do!) and I'm a little concerned they'll end up with 1) people who don't realize they can go past the person who has stopped to look at stuff or 2) people who don't want to let people pass them even though they've stopped.
That's really the only issue I see. Though I've only been in a long line for HM once, so I'm wondering why they chose that ride to add an interactive queue to. Or maybe it's just less busy during Halloween/Christmas stuff? (Those are the only times I've gone.)
