I have a GoPro pole, but am always very conscious of those around me, and how I might be affecting their view or personal space. I encountered far more kids going on shoulders at the last minute that ruined my view of the castle/show/parade. I enjoy using the pole to get some great candid shots of my group when they aren't posing for a picture. Hold it unobtrusively like you aren't shooting anything at all (and not extended out), and I can end up with some great shots when they aren't busy getting in a specific pose. Of course, you also get people flipping the camera off in the background, but that is why I shoot burst shots and time lapse. You can get a bunch of images and shake out the crap for a great shot. Used PhotoPass as a supplement last time, and that was great, but we get so many more interesting shots with our cameras, too.
It really is about people being respectful using the equipment or kids on their shoulders. There is no end to people unaware of those around them...
