We just went there as out of state residents but we have family in florida. If they paid it was discounted and yes you needed a valid Florida ID.
No u must show a driver license or ID. You can go to the DMV before you go to seaworld, you gotta get a Florida license at some point anyway. U can order online but there are frequent times they will ask to see proof of address at the gate.
I am pretty sure they require driver licenses and if you go on the site there are discounts for Fl residents and probably now for non residents .
