My first theme park experience was at Busch Gardens in Williamsburg, VA when I was three. Know what I remember? Feeding ducks on a bridge. That's it. I don't even remember that it was record high teperatures for the day, though if you look at the pictures, I'm crying in all of them from heat fatigue.
I first went to Disney World when I was six or seven. And that I remember. All my love of the classic rides stems from that trip.
Personally, I find it absurd to take a 2 or three year old to the park. They simply don't know what it is, get cranky and don't remember it anyway. If I were ever to have kids, I'd wait to take them to WDW until they were at least 5 or 6.
My Love's first trip to WDW was when he was 2 1/2. He doesn't remember anything either. If it weren't for dated photos, as far as he's concerned, he never went.
Instead of spending that much money, and that much of a large-scale trip at that age, I'd wait. There's a big difference between taking a 2 year old to the zoo or a park, versus to Disney World. I'll never understand it and just won't be convinced by the arguments that the kids have a great time. Yeah, kids have a great time playing in dirt too.
*shrugs*
I'd wait. But that's me. Most people are selfish and take their kids way too early because THEY want to go and take their kids. They don't do it for the kids, they do it for themselves. Waiting until everyone can have a good time makes much more sense to me.
