Antarctica - Empire of the Penguin is a motion base ride in Rides at SeaWorld Orlando. Readers say... skip it.
This reconstruction of the park's old Penguin Encounter opened in 2013, and features the United States debut of a "trackless" indoor ride system. Located in a pavilion decorated to look like Antarctic ice, you'll be following a young animated penguin named Puck through his first year of life. You can choose a "mild" or "wild" adventure, though the only difference is the amount that your eight-person vehicle will spin and bounce during the ride segment of the attraction. There's no height restriction for the mild option, but everyone in your group must be 40 inches or taller to choose wild. On board, your vehicles will "dance" with other vehicles in two "ice" caverns before regrouping to watch Puck's first dive into the sea. From there, your vehicles turn around once more to reveal a real penguin habitat, which you'll get to linger in at your leisure after exiting the ride.
Note that there's no glass separating you from the dozens of penguins, representing multiple species, which means that SeaWorld keeps the room very cold — less than 40 degrees. Bring a sweater or jacket if you want to spend more than a fleeting moment watching the penguins before rushing outside. Also note that SeaWorld keeps the exhibit's lighting on the Antarctic calendar, meaning that it's nearly dark for most of the day during the North American summer, and brightly lit during Orlando's winter. That makes the winter months a far superior time to visit this attraction.
