The tour guides are the zoo staff from the original Zoo Tycoon. They are able to guide guests to animal exhibits in the zoo. When a tour guide makes it to an animal exhibit, he or she will speak to the guests about the animals. The tour guides can also be eaten by dinosaurs. As a tour guide can be eaten by dinosaurs, this results the player unable to recover a tour guide who was eaten by a dinosaur.
If the player renames one female "Rosalie", the salary cost will change to zero.
