Generally I just peruse these boards and don't have much to say except this time. Sorry =)
For one I agree, those Wheelies things are annoying and appear quite dangerous. Working in retail I have seen a few kids get hurt or collide with other guests in my store. Drives me batty.
To the one person that mentioned that the electric carts are a medical need and not a fad, agreed! Lots of guests at Disney parks across the world need them, however we all know and have seen many who do not. This is not the place for THAT discussion. However I have seen MANY MANY MANY inconsiderate folks running around with those electric wheelchairs, strollers, or anything on wheels. I have seen quests use strollers as weapons or plows to get through crowds in WDW or even Great Adventure.
Going into the topic of parents allowing their kids to do whatever they want, I have seen many parents give the reply of... "This is Disney." Err what? Does that give them a license to do whatever they please? Granted Disney is a place for children (although I really don't agree cause it's for everyone), it doesn't give them that right to be stupid. I have also seen parents treat Disney as if it were there home where they can throw trash on the ground, sit where they wish, or just deface property. ?
Now onto the more comedic side of this enormous post. A few years back my father and I were in the stroller area of PoTC when we hear a child in a stroller screaming bloody murder. The mother is behind the stroller and the father was holding a bottle. We hear the kid scream "I don't want to drink it," and the father replies by squirting the bottles contents in the kids face, and saying "Drink it drink it drink it." My father and I nearly died from shock and unfortunately even laughter. We almost look for that family everytime we are in Disney.
Some people shouldn't be parents. There should be some sort of test. =)
