"'member, if you rename a guest Albert H (birds scare guests), try to do it when you only have a few guests in your park, because the birds don't go away until everybody leaves.

-Don't rename your exhibits "Xanadu" or "Cretaceous Corral" until the exhibits have already have their default names (Exhibit 1, Exhibit 2, etc.)

-you can name a quest Charlie Peterson to get "more" foliage, not all of it, and this cheat can only be used once.

-don't get a Tricerotops until you have their favorite tree, the Savannah Grass Tree, or they won't ever get happy. this works with other typical animals who seem to bite the hand that feeds them.

-this isn't a cheat code, but i had fun with it; get a group of your favorite animals (i chose Gazelles) and give them the names of your friends. try mixing males and females and name them the name of your mother or boy/girlfriend, and watch them have children together.

-if you want to get more and pay less, this is what you can do; make tiny exhibits of about 3x3 or 2x4 and put a pair of a species in it. if you tweek it properly they'll like it just as much as a normal-sized exhibit. the easiest ones (if you first start out) are the lions, the Bengals, the zebras, the gazelles, and the Grizzly bears. remember to put plenty of zookeepers though; if one animal takes a dump, then the exhibit suitability will drop dramatically.

-be sure to put lots of animal houses around, because, if you haven't noticed, some of them add to the guests' happiness level. also, put lots of observation areas for your exhibits, because it raises the happiness of your guests too.

-raise the entree price to $100. it doesn't affect the guests atall, and with every ten guests that show up, you earn one-thousand dollars.

-if you want to keep the guests from getting hungry, put things like pop and candy machines in random places, so that you don't have to make fancy picnic areas all over your park.

-if you have a problem with your guests "escaping" or in other words cutting across the turf to other places, be sure to put fences or flowerbeds around the paths. the people won't run off, and they'll appreciate the scenery.

-don't forget to place maps around your park; if they get hungry, and you scolding them because you know that you've put food stalls in obvious places, maybe your problem is that you lack maps, and the guests don't know where to go.
