Please, please, do not blow bubbles in line! People who do not like them are trapped and can't get away from them! Bubbles are not camera friendly, nor are they I-Pad friendly. They can also stain clothes, and some people are very allergic to the solution.
Not to mention, a little one can try and chase a bubble and end up falling down, or tripping on a queue chain, or running into other guests. And if the solution gets on the ground it is very slippery!
Please, no bubbles in line!!!
This please! You can usually avoid them around the park if you want but you are trapped in line.
