It's been said before but I'd like to clarify. The Jurassic Park in IOA is not Isla Nubar, or Isla Sorna, it's actually called Isla Adventura; located in Orlando, after the previous two islands. If you watch the Queue video at River Adventure it explains it all. Also, in that large circular area of River Adventure's queue theres a giant scale model of Isla Adventure. On it you can see labels for 'River Adventure, Camp Jurassic, Discovery Center, and Triceratops Encounter' interestingly enough there are also labels for attractions that didn't make the cut, 'Jeep Safari, Helicopter tours, and Carnivore Paddock and Herbivore Paddock.'
