SeaWorld is a very wonderful place. It's amazing to me how many thousands of wonderful animals that they've saved in the ocean. So much animal conservation. I believe they need to advertise this more. First off, I would definitely recommend Discovery Cove. We did a dolphin experience there which is a lot of fun, or you can just swim in the park all day. It's a private part of Sea World where they only allow a certain number of people there a day. At Discovery Cove, it used to be that you can eat and drink all day (not sure if that has changed. At the Sea World park, we did a penguin encounter also. And one ended up nipping my wife. Not much of a nip. So neat to see them up close. It may end up paying you back also if you get a membership to AAA. Pays also if you end up locking yourself out of the car. They also offer discounts to Disney and a plethora of other places. So, if you do a combo of Discovery Cove and Sea World I would allow 2 days. Otherwise, just one day. Have fun!
