Disney's parking fees are now $15 per day. (If you hop parks, you don't have to pay more.) If you're staying at our group hotel or at another Disney resort, you won't have to pay the parking fee.
I think it was $14 per day when I posted this year's info, so if you see that anywhere, please yell so I can change it. I think I've updated it everywhere, but not sure.
The parking for SeaWorld is $15 per car, and isn't waived for educational groups.
The Universal parking fee is $16 per car, and isn't waived for educational groups.
