Beyond the main gate is the Information Center where you can pick up maps and daily schedules of shows. This is where you can book behind-the-scenes tours - but be sure to arrive early as tours have a limited amount of spots and tend to book up quickly. Reservations for the Dine with Shamu buffet, the Hawaiian Aloha Polynesian Luau and other restaurants can be made here. The Information Center is also where you would rent strollers and wheelchairs.
Once you receive your map and schedule, take some time and orient yourself with the layout of the park. This will help you make the most of your day at SeaWorld. Most shows and exhibits can be seen in one day, but seasonal crowds and long lines for the rides may have you considering an additional day at this park.
The three thrill rides at SeaWorld, Wild Artic, Kracken and Journey to Atlantis are popular and generally have long lines. Arriving early may get you a jump on getting through one or two in a timely fashion.
