More visitors:
If you want more people to visit your park, build four or five entrances on all 
different sides. 

Enable the "Seal Of Approval" code to get five stars. Put as many entrances as 
you can, then open your park. The chopper should appear instantly, and lots of 
people should walk through the entrance.

Create a no enclosure safari (still fencing off carnivores). Place a large square 
fence around the area where people arrive in the space. Fill it with dinosaurs that 
do not eat humans, then create a small gap in the fence to let humans pass 
through. Place musters there to stop dinosaurs crossing. On the other side of the 
fence, continue building a fenced-off dinosaur park. If done correctly, your star 
rating will keep going up. 

Avoiding visitor deaths:
Never build a Safari Adventure in your T-Rex cage. The visitors inside of the car 
will not live too long.

Never put more than one T-Rex in one cage. One will be killed and the other badly 
injured; and the visitors around the cage will get scared to death. This costs you a 
lot of money, for the T-Rexes and the fines.

Saving money:
To save a little money, build a small enclosure around a hatchery. When you hatch 
a dinosaur, sedate it, and move it to its cage. 

Build your concessions and park entrances inside a fence. Then, run a fence 
through the middle of the land and make some hatcheries. Also, put some Auto 
Lures near the fence so that people can see the dinosaurs. This saves time and 
money, as you do not build individual cages. 

T-Rex: DNA:
To get some T-Rex DNA, unlock Judith River Formation B and put your dig teams 
there. They will find T-Rex remains. 

Spinosaurus: Rampages:
Spinosaurus always go on a rampage sooner or later. Be prepared to kill one and 
hatch a new one. Never put more than one Spinosaurus in a cage. If you do, one 
will go on a rampage in the first few months. Never put a Spinosaurus in with other 
large carnivores. The Spinosaurus or the other type of dinosaur will go on a 
rampage.

Rescue The President level:
Shoot the Raptors first. Then, run fast and escape. Once they are all dead, take 
out the Spinosaurus and then any desired dinosaur.
