User blog comment:John Alfred Hammond, CEO/Civilized Talk on the Pointers to JP:TG as Canon/@comment-17754282-20141126213746

The toilet situation is hardly the same thing as the Marine Facility. Toilets are a given- they are necessary so they are bound to be there. On the other hand a Marine Facility is not essential, so it's wrong to assume that there is one. The problem with JPTG is that although is calls itself a sequel/tie-in/whatever, it had to change things that were already a part of the canon of the films in order to work - case in point: The Park Map. Not only does JP:TG erase Metriacanthosaurus, Segisaurus, Baryonyx and Proceratosaurus from the island, it also relocates several dinosaurs which, in the cases of Triceratops, Brachiosaurus and Gallimimus at the very least, causes continuity problems within the fim. In the film they passed the paddocks for Dilophosaurus, Tyrannosaurus and Triceratops in that order before being forced to turn around and head back to the Visitor's centre. In the original brochure that works fine but with the map provided by the game it could not have worked like that as Triceratops was relocated much further south to occupy the place previously help by Gallimimus and Brachiosaurus - if it was there they could have just done a lap around the Triceratops enclosure and headed right back to the visitors' centre without having to go anywhere near the Tyrannosaurus paddock. The first animals that Grant and the kids encounter after escaping the Tyrannosaurus are the Brachiosaurus herd. Again, this is possible with the original brochure as the Brachiosaurus herd is located near to the road that the Land Cruisers took on the tour. With the map from JP:TG the Brachiosaurus herd is much further away from the Tyrannosaurus paddock, indicating that Grant and the kids travelled much further in just a few hours on that one night than they otherwise appeared to - perhaps that one is not such a bad thing, until you consider the relocation of the Gallimimus herd. The map for JP:TG moves the Gallimimus herd much further south, making a very large gap between them and the Brachiosaurs, indicating that after encountering the Brachiosaurs, Grant and the kids not only went much further south than they needed to and but also had gone completely the wrong way. In fact, if the game's map is to be believed, then the fence that Grant and the kids climbed should have brought them out near to the Helipad, not the Visitor's Centre. Then there is the decision to include a flock of Pteranodon on Isla Nublar. Shoving an aviary in is one thing, having them free roaming is never satisfactorially explained. InGen obviously knew that these creatures needed to be enclosed, JPIII confirms that much, not only due to the possibility of them flying off but because of their aggression (note that the ones in the game were the ones seen in JPIII, not TLW). For their presence to make any sense they must have been in an aviary of some kind, but how did they get out? They obviously could not have escaped even when the power went out because the ones in JPIII remained securely locked away despite there being no electricity on the island for many years (during which time every other carnivore escaped their enclosures and wandered freely amongst the herbivores.) This indicates that someone either let them out or that there was no aviary and Telltale just got sloppy.
