Don't flame me for this, but I did it when two of my kids were 3.25, and they're tall!
That was in the '90s though, Disney as gotten a bit stricter since then. Nobody ever said anything, but I believe now so many people try to get their 3-year-olds in for free, they have to ask a lot of questions.
You could try it, I don't think it's a huge deal, but you may run into some trouble. I'm going to stay neutral on this issue. At least your child will have only been three for a few weeks, when my niece was a few weeks shy of her sixth birthday (obviously she's pretty short) my BIL lied and said she was 2.5 to get the free ticket!

At DLR that's what I do, just hand the CM all three, while one of us goes through the turnstile and the other adult and DS go through the gate thing. They have no choice but to scan it!
