In my experience, the guests would much rather see an exhibit filled with happy animals than to go to an attraction. We all know that the guests enjoy the attractions - Aviaries, reptile or insect houses etc, but how much do they really like them? This one I'm unsure of. When you DO put in these things, be sure to make them easily accessible to the guests. DON'T put in too many restaurants/rest areas. While they have these needs, they don't necessarily want them filled My biggest problem when I first started playing Zoo Tycoon is that I could never make my guests happy no matter HOW many restaurants and rest areas I put in! Truth be told, your guests would rather have all their needs at ZERO than to have too many places to fill their needs! Therefore: Guests have needs - hunger, thirst, bathroom and energy. I recommend putting the gates to exhibits close together (if not touching), so that the zookeeper can easily go from one exhibit to the next. This will prevent the exhibits from getting filled with too much poo (which the animals really hate), and the presence of the zookeeper gives the animals a happiness boost. Keep a zookeeper assigned to the exhibit. If they get crowded, find the newest animals in the exhibit, make sure to leave at least one male and one female, and sell off the older animals - this will prevent losing animals to old age, thus giving you a nice financial boost Nothing will anger an animal more quickly than being crowded by their own species. Be sure that you don't have too many animals in your exhibits. I recommend always keeping a tile between your pathway and your exhibit, since even the most social of animals will feel crowded by 1000 guests meandering past their exhibits Also, NEVER put your pathway directly touching the fence of the exhibit on your shy animals. This is especially important on your shy animals such as pandas, many of the leopard species, etc. If you see that your animals are feeling crowded, use a fence that your guests can't see through on much of your exhibit, leaving only a few viewing areas where they can see in. Make sure your animals are not feeling crowded by too many guests. Reach for that 100% suitibility rating on your exhibits! A high suitability will make for happy animals.

This isn't going to help at all, and may even have the opposite effect, if your animals aren't happy. Make sure there are animals visible from every which way the guests may happen to turn.
