orljustin, I recant my statement about the bleeding, you did say you laughed when they fell, and not when they were bleeding. Understandable... You see an out of control kid sleigh ride through a group of kids like bowling pins and you laugh... turns out one of them needs to have pins put in his shin for a multiple fracture... no longer funny. But indeed there was laughter.
As to the breaking the rules. Nope, don't expect a letter, but I would want to hear it from a CM. And from them I was 1 Yes and 1 No. I checked the back of my AP, no comment there and didn't see it posted at the park. I'm not a rule bender (Believe Me! I paid full price for a 38 month old one year) But I knew Disney's policy is posted 3 year old. I guess I haven't read every word on disney.com, but I have listened to every announcement, and haven't noticed any signs either so yes when Disney tells me no heelys, then no heelys. We have no plans to go back as of now

but when we do I will get an answer from "Disney" if I need one (probably won't because I'm not going to be pulling them around all week again (and I don't let them skate in the parks)
Aside from WDW to any parent who won't let their kids use them... that is a personal decision and as a fellow parent on to be respected. But I just have to wonder do you let them go to skating parties? what about riding a bike? sleigh ride? use trampolines?... ask an orthopedic surgeon about trampolines someday!!! Will they be allowed to play sports? drive a car someday? Ok I'm carried away, but I'm just wondering where they rank by some parents. I let my boys (5 and 7) do all of the above except trampolines. (ok I don't let them drive cars yet) But I'm wondering where heelys rank. Again you are the parent and if you don't want them to do any of it, that works, you are the boss. But if you are going to pick and choose an orthopedic surgeon would be the one to ask... and trampolines will rank lower than most anything. I actually asked out Ortho about my sons heelys she rolled her eyes... I got nervous, and said "Oh do you see a lot of injuries" She said "No, they just annoy me at the mall" I thought it was great.
Ok last thing... for the record last trip... 7 days... Heely injuries witnessed 0, ECMs?
ECV? E?? What the heck is it again? The rechargeable "wheelchairs" 2 (1 minor and 1 major) I know it's not the same thing, because heely are optional (and possibly "illegal") But I can guarantee more people are injured everyday at WDW because of those than heelys. (yes, I know not relevant, but still true)
