As someone else has already said, this is a common hot button topic on this board.
Allow me to summarize the entire thread, so that you won't have to read 20 pages looking for people that are flaming you, and having you respond. . .
You: Kid is an inch too short
anonymous poster (ap)1: Buy shoes that will increase height
ap2: they can and will measure barefooted if there is a question
ap1: no they won't
ap2: it happened to my daughter
ap3: it is a violation of DIS rules of usage to recommend or provide ways around disney rules or regulations
ap1 (to ap2): it didn't happen
ap4: just put her hair up in a hat
ap5: the rules are there for safety
ap2: you're right, I wasn't standing there when it happened.
ap4: those rules have wiggle room
OP: um, this is starting to really get out of hand, I don't want to do anything that will get people angry
ap5 (to ap4): are you an engineer? did you design the ride?
ap1 (to ap5): those rules have wiggle room (a lot of times people that engage in side conversations miss what others post)
ap6: I think that OP should be ashamed of themselves for even trying to put their precious little son/daughter/miniture pinscher into a dangerous situation like that. You should be arrested, thrown in jail and sterilized.
ap7:
ap8 (now on second page): buy some large soled shoes (person didn't read anything on page one.
OP: you don't know me, where do you get off telling me how to parent
And I think you get the picture from here.
Basically, all the points have already been made in the first page, and then it just becomes a complete free for all. People get called DISney Cops, others lament how the people on the DIS have become so much less friendly. Someone will question why people feel their children are entitled to violate the rules.
Really, the above scenarios can be substituted for several different questions (ie line holding/fp fetching/potty breaks/heelys/re-fillable mugs).
It's what makes the DIS keep going.
Enjoy.
