How To "Try" To Get Rid of hungry guests.
Hunger Bug. There is a patch that fixes a bug which caused guests to remain hungry or unhappy even if they are standing near a
food stand or something that should increase their happiness. Get the patch via the Get New Items menu from the ZT main
menu.
Not enough food stands.Maybe you add more food stands or perhaps they are all centrally located. Try having one small food court with a few stands, tables and trash cans. Then disperse more stands throughout the park. Be sure to add a table and/or trash cans when you place stands.
Less filling food. Try to place more filling foods such as hotdogs, hamburgers and pizza (when they become available) since these fill guests up more (and keep them full longer) than ice cream or soda/snack machines. Place the more filling (and more expensive) foods in more high-traffic areas and fill in the gaps with snack foods.
Tips on Making A Profit
Jack up the price. Your entrance fee, food and drink prices, souvenir prices, and attraction prices (rides/ shows/exhibits) can all be adjusted. So add a buck or two to the price and generate a little extra revenue. I haven't heard guests complain yet, but if yours do, let me know what happened.
Expenses vs. Income. Make sure your attractions and food stands are raking in more money than you're spending on upkeep.
Animals feel Crowded by guests
Replace see-through fences with solid ones.. Many animals, including several of the cats in the Big Cats scenario (Intermediate), begin to "feel crowded by too many guests". I solve this, of course, by replacing the "see-through" fences with solid ones (concrete, or wooden). I make three of the sides closed and one side open and leave only about 5 sections of that fence open. Then place viewing canopies over them to show guests where to stand to see the animals. This usually works well with the "shy" animals.
Redirect traffic. Try not to have paths wrap all the way around an exhibit and make sure you keep traffic moving, so to speak, to avoid big pile-ups in front of a certain exhibit. Use intersections that lead to interesting attractions (i.e. Animal Theater, or Animal House)
Making a little "Fast Cash"
Hike up the zoo admission fee, theater and food prices.
If there are plants, trees or rocks on the map that you won't be using, sell (demolish) them for fast cash.
Terrain on a Budget
Watch Animal Happiness. Don't add any more special terrain than is necessary. Watch those little happy faces and add terrain one block at a time and when the happy faces stop, stop spending cash on that way expensive snow or rainforest floor.
Start with dirt. Most animals like a mixture of terrains. So, start with the cheapest terrain and then go back and add in the more expensive stuff.
Some Possible Solutions to those "Angry Guests"
Animal Treatment.Many guests are real activists when it comes to how animals are cared for. If you have a lot of animals and not enough zookeepers, animals will not be fed as often, and their exhibits will not be as clean. Remember, it's not the number of exhibits each keeper takes care of that matters, but the number of animals involved.
Needs and Wants. Angry guests are often those who cannot find what they need or want (Drinks, bathrooms, trashcans, etc). Be sure to have a good number of guest necessities evenly distributed throughout your zoo.
Maintenance Workers
Maintenance Workers will try to do the same job at once when there is plenty of work to be done elsewhere.
Maintenance Workers will pass up full trash can after full trash can to repair a fence on the other side of the zoo.
Maintenance Workers occasionally do nothing at all.
How to deal with this:
Don't use them. Some players choose not to use MW's and get around it by fixing fences themselves (add a new piece over the decaying piece) and using restaurants, which generate no trash, instead of using food stands with trash cans.
Don't have too many. Some players opt for one or two MW's in the whole zoo and use restaurants and fix fences themselves (see above).
Ignore the problem. Sometimes it's the only way to deal :)
Boost Exhibit Ratings using Foliage
Make sure the grid is on. (CTRL+G) Place a tree or other plant in a square one at a time until the animals give a sad face. Then delete the last one and fill up the squares that already contain foliage. Many trees/bushes can be placed four per square, others can't. Animals don't consider this as more foliage, but they like it better. This will increase your exhibit rating dramatically!
Animal House Attractions
Once you've researched a special animal house attraction (i.e. Primates of the World for the Primate House), click on the house to open the info box. Then click the notepad icon and select the attraction you want (The attraction must be researched first).
Animal Happiness
Free Space! Who'd have thought this would be an issue, but it seems that animals have a specified amount of open area they prefer. For example, Siberian Tigers want 50% of their exhibit space to be open area (i.e. put the trees and rocks toward the fence). It's strange yes, but just try it. If you've got an animal who has everything they need and more, try moving the foliage to the outside of their exhibit and see if that works.
Entrance Happiness Boosters
If you can hike up your guest's levels from the moment they enter the zoo, your job will be a lot easier as they walk through the zoo, since you won't have to try so hard to make everything look great.
Try these things:
Use the brick path (or the yellow brick path if you've figured out how to unlock it) at the entrance, a couple or even three tiles wide if you have room.
Place statues, fountains, and pleasing foliage near the entrance.
Consider a courtyardwith flowerbeds, benches and a fountain or vending machines.
Use the tour guides. Yes they're expensive, but just buy one and use the Tour Guide Cheat so they're free, then hire more. (Make sure you use the tour guide cheat on a female guide or else it won't work) Guests love them.
