There is no Seaworld in Chicago. However, there is the John G. Shedd Aquarium on Lake Shore Drive at Museum Campus.
There are several SeaWorld Theme Parks. See link below for their website.
Depends on which Aquatica you are asking about. SeaWorld Orlando/Aquatica- Aquatica is right across the street from SeaWorld SeaWorld San Antonio/Aquatica - Aquatica is located right inside of SeaWorld, so to get into Aquatica you have to get into SeaWorld SeaWorld San Diego/Aquatica - Aquatica is located in Chula Vista, which is about 45 mintues south of SeaWorld San Diego.
First, by visiting SeaWorld's official site. They have contact links there. Also, their address is 7007 Sea World Drive, Orlando, FL 32821 and their phone number is 888-800-5447.
