MGN ORLANDO, Fla. (AP) Adventure rafting is coming to SeaWorld Orlando. The theme park announced Thursday it is building the Infinity Falls thrill ride. Park officials say an elevator will lift each raft and then launch it into a river 40 feet below. They say it will be the world’s tallest river rapid drop. The ride will have a rainforest river theme, and park officials say it will be the centerpiece of a new area of the park recreating a rainforest canopy. Infinity Falls opens in summer 2018.
