The current policy for out of state visitors requires proof of vaccine, does this include for children under 16 years old?

Proof of vaccine or proof of negative test up to 72 hours before visiting Sea World for all out of state guests ages 3 and up.

I'm not sure, but I believe it's for everyone over the age of 2?

I really don't know, but they'll check your temperature when entering.

Check website. We got tickets from a CA resident. :)

I went last month didn't need proof of anything, just needed to purchase online

Children can't get vac so it doesn't count for them.

Yes 3 and up
