I've seen that 40" doesn't seem to always be 40" in the Disney Parks. I've read the threads about kids being measured 40" at the start of the line but less than 40" when they hit the end. And that 40" in bare feet kids have even had problems being too short for 40" rides in sneakers in Disney.
I'm curious to know what your experiences were in IOA and Universal. Last time we went, our barely 40" child easily got through the Spiderman line easily. Six months later, he got through the 42" for Men in Black about ten times though I thought he was about a third of an inch below 42" in his shoes. So my experience was that there was no problems at all - but that was three years ago. My daughter is currently a smidge under 40" in sneakers - like less than a peice of paper width below. We're leaving in few weeks so I expect her to grow that smidge but not expecting much more. I'm not about to do anything special to get her taller other than to tell her stand up straight and do the 40" rides in the morning.
