BUBBLES!!!!! I hate those stupid bubble guns that Disney sells, or the even the regular bottle of bubbles. My husband wears glasses and I have a nice camera. The bubbles pop and leave a residue on lenses that doesn't simply wipe off. I also don't appreciate the soap on my clothes, and by the way, some people are allergic to the soap. No one wants hives or a rash on vacation. I get that you want to keep your children entertained while they wait in line, but queues have way too tight quarters for you to be blowing bubbles all over unsuspecting strangers around you. You can play with bubbles to your hearts content at home, but please stop blowing bubbles at the parks.
Also, while I absolutely expect to run into children having a good time (and sometimes not having a good time) at Disney, I still expect parents to you know, parent. Like DisneyJediMaster said, it is not okay to let your kids run around disturbing other people. Having kids does not allow you special privilege at Disney. Kids will be kids and laughing, crying, even some screaming is par for the course, but it is your job as a parent to teach your kids how to behave in public. Running around tables dodging other guests, climbing on things that they shouldn't, pulling out leaves or flowers... these are all unacceptable behaviors and I will give you the "stink eye" right back if you don't control your kids. You are not the only one paying to be there, you know.
