A permit spotted by WDWMagic user danlb_2000 seems to show the ride layout for the Na’vi River Journey coming to Pandora in Animal Kingdom.
A closer look at the permit suggests that the ride layout will be the portion in blue with the show scenes represented in peach.
We’ve highlighted where we think the load/unload area will be in red and the boat storage area in green.
Further analysis of the permit shows that the ride will have a little less than 1/4 of the amount of water Pirates of the Caribbean has in Disneyland. Using that as a benchmark, that could put the ride at 4 – 5 minutes long, but this is all speculation.
