Sorry to burst your bubble...but yes, I use the bubble guns and we love it. We typically pull it out only when we're waiting for parades, fireworks, and in line at the opening of the park. Mine is a light up bubble gun so we typically only carry it around at night.
My guess is only a small percentage of people (higher here on the Dis) dislike them. Everytime we've brought ours out, we get smiles and the kids around us are thrilled. We also do nasty, annoying things like hand out glow in the dark bracelets.
One time we were waiting for MSEP and my son played with our bubble gun for about an hour. The vast majority of it was piled on one specific patch of ground where he was building bubble "towers". We engaged the kids next to us and kept them happily occupied during that hour too. I did monitor his use and we did our best to ensure he wasn't annoying folks next to us. We used it at Fantasmic where we went an hour and a half early. It was so much fun and we were joined by quite a number of kids.
Now if someone hates bubbles, all they have to do is come up to us and politely say, "I have a skin allergy - would you mind not blowing the bubbles near me?". Or "The bubbles are affecting my camera - would you mind blowing the bubbles in a different direction or a different location?" or else "The wind is blowing all the bubbles in my direction and I'm getting coated in bubble liquid. Would you mind doing this somewhere else?". We would stop, move, or monitor our use much more carefully.
Cast members blow bubble guns all over the place and few people are annoyed - don't see why we can't blow bubble guns ourselves.
I don't understand why the tiny minority of people who have problems with bubbles can't speak up politely. The vast majority of people will likely be happy to stop if spoken to nicely and politely. The tiny number of rude people that won't stop with a polite request.....won't care even if they are ranted against on a message board. there's nothing much at all you can do about those rude people other than avoid them.
Now, if someone yells at me about my bubble gun, it is quite possible I will ignore them and keep playing with it as there are no rules at Disney against them. Hey - they SELL them so they obviously WANT guests to use them.
