My son was 2 weeks shy of turning 3 when we went a few weeks ago. We went to all 4 WDW parks and ony once was he asked his age. He's a fairly tall and weighs like 55 lbs. Like some of the other posters said, having to pay for any of the meals would have been a waste because he is a very picky eater. While everyone was enjoying our dinner at Ohana's, he was enjoying his bag of Cheetos....
OP, make whatever decision you feel comfortable with. The only thing I'd worry about it what your kid will say if they ask her....

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!
Because she liked to pretend she was as big as her brother, I guess? I told the lady, "No, she's 2 and will be 3 next week" and the lady gave me a very unbelieving look and let us in.
My personal philosophy is that "the moral highground" argument is quite silly. It's not as if you're lying under oath!!
I would certainly not hold it against someone for missing the cutoff by a few weeks. (Now, the BIL who missed it by 3.5 years is another story! 
Me included, I have the expired points to prove it.
