I hope you can forgive a bit of copy and paste but there’s no sense in typing this out again. And after using this strategy multiple times in succession I can confirm it’s effective.
I used Jurassic Park as the era instead of Jurassic World and used Isla Matanceros.
The thing is, JP has significantly lower requirements on visibility and the number of unique species required since fewer are available. As long as you have the binoculars researched, the dinosaurs will count as “visible” if they’re anywhere near the tour vehicles.
In Park mode you also need substantially fewer facilities, I built a single Tour and put all the paddocks around it. I built extra hotels to ensure the facility rating was 5 stars without issue.
I did end up building more than one of each guest facility, only because the arrival helipad, visitor center and aviary where far enough apart to warrant it.
Also, you ALWAYS want to have two contracts from Dr. Malcolm as his are almost always timed contracts to keep the power on and prevent carnivores eating anyone. And save before accepting any contract from anyone else; you don’t want to end up with contracts you cannot complete quickly when you’re short on cash.
Having the constant income stream from Dr. Malcolm’s contracts will meaning having money to burn to incubate the more expensive dinosaurs and build the best possible tour.
Because there’s no time requirement, so long as you make use of Dr. Malcolm’s contracts you’ll always have extra cash even with the gradually increasing Hammond Foundation fees. Because of this, it’s worth it to invest in having a full genome before adding a new species to the island, as well as using the shark DNA to maximize their life expectancy.
And do yourself a favor, the SECOND you hear about an approaching storm, immediately, WITHOUT HESITATION, send your Rangers to tranq your Raptors and T-Rex. Make sure you have two teams. If you put up electric fences the Dilophosaurus won’t be able to break free, and the Ceratosaurs and Spinosaurus don’t care about a storm enough to rampage easily, same goes for Baryonyx. The time spent trying to chase them down after a storm and fix fences is time and money wasted.
Stegosaurus WILL be your biggest source of drama as they start to panic as soon as there isn’t 5 of them in the herd, and they will tear down fences fast if not kept happy, so always keep 6 of them in a paddock at once. Otherwise you likely won’t be able to release a new one in time before the others lose all comfort and start attacking your fences.
And yes, you only need the one tour. Keep a fence between the tour vehicles and the dinosaurs. The vehicles can see through the wire fences so it will not affect dinosaur visibility.
I ended up not needing every last species since heavily modifying each dinosaur substantially increases their rating reducing the total number needed, but not the required unique species. This results in not needing to mass produce dinosaurs to par out your score at the end.
