Well Discovery Cove is a separate park that is part of Sea World,they have 3 parks in Orlando,Aquatica,a more traditional waterpark with some attractions that incorporate animals like the Dolphin Plunge slide.Discovery Cove which is the all inclusive park where you can swim with dolphins and the original and main park Sea World.I would say if you visited Sea World today compared to 10 years ago you would be amazed by the amount of changes to the park.You have 2 major rollercoasters and the Journey to Atlantis water coaster.A pretty new area with shopping and restaurants called the Waterfront.Restaurants like the Sharks underwater grill where you can dine while watching huge sharks swimming by.Many of the shows have also been improved over the years.As well as the much improved kids area with rides such as a junior Shamu themed rollercoaster.During busier periods they also have a fireworks/show in their lake visible from many areas around the lake.And of course you can also visit the two newer parks,Discovery Cove and Aquatica.
