At some point though, you have to make allowances for real-life practicality. The only way to stay completely true to this new canon would be to demolish the whole of Jurassic Park and start again. That would be excessive and unnecessary. Ultimately, no one thinks they're in Jurassic World. They think they're in IOA, and if there's a cool new Jurassic World ride for them to enjoy alongside the Jurassic Park rides they know and love, they won't be complaining about a metastory 'plot hole'.
