Do you have to buy tickets in advance or can you pay at the entrance

both, but in advance saves time

You can pay at the entrance

In advance requires reservation

Pay in advance or at the park.

Both.

U may want to check for discount & pay earlier so u can skip the wait

By in advance and make reservations is best to make sure you get in.

You can pay at the park with live person or with a self service ticket machine....i purchased my tickets online and in advanced

Either way but printing and bringing gets you in the park faster

Either way, would recommend in advance though

At this point either way.

You can buy tickets at the gate now

Think you need to get advance reservations so most likely need to do that with a ticket in the SeaWorld website.

Can def buy advance

You can pay at entrance

You can do both online may have deals though.

Pay there

Both. Online is quicker
