Get that. I am vertically challenged. I pick my spots where a 6+ dude or dudette isn't standing in front of me.
Having a 6+ dude strap one of those puppies on and lifting his kid atop his head certainly wouldn't be a crowd pleaser as any show or parade would start.
Actually my DH & DS are both extremely tall. They don't often get shunned to the back, they are pretty gallant men, they often offer the vertically challenged the opportunity to stand in front of them, I guess it is all in how one approaches that situation. Having had a couple of kids my DH quickly felt for kids that couldn't see around him, my DS just learned by example. They both pop up from seats on buses too for ladies, children and elderly.
My DS has said that type of etiquette is pounded into their heads at Disney, in costume or off duty. I've seen my son pop up on buses, boats and the monorail. Once he popped and the lady that sat down next to me was one of his trainers years ago.
