SeaWorld Orlando on Tuesday unveiled the ride vehicle for its new motion simulator in its Antarctica expansion this spring - a ride that will let guests pick the intensity level and variables that change the experience with each ride. The saucer-shaped vehicle, right, will carry eight passengers on a journey through Antarctica that combines a mobile simulator platform and a trackless navigation system. Riders can select a high- or low-intensity ride, and the cars move along different paths making each ride variable. "There's no predetermined route, making (the ride) very unpredictable - like Antarctica," SeaWorld's creative director, Brian Morrow, told USA Today. The ride will open with Antarctica: Empire of the Penguin in the spring.The queue will allow visitors to "program" their vehicle before boarding.
