OK, here's an interesting twist. Universal is running a promotion, where if you buy an adult 2 day/2 park pass, you get a free child's pass of the same. So, if my wife and I both buy the 2 park/2 day ticket, we'd get the free child's ticket for our son, and the total would be $218. If we buy 2 adult 1 day passes and 1 child's 1 day pass, the total would be $178. So, we're talking about an extra $40 for all 3 of us. Almost seems silly not to do it.
