Large wheel with 16 self-righting chairs, each holding two peeps.
Each time a new pair of guests enters, the Ferris Wheel spins around the number of times indicated in the Operations options tab, then goes to the next chair and unloads. This process is repeated, meaning that a pair of guests really goes for the number of rotations specified times 16. This can add up quickly, so keep that number low, or guests will complain that they want to get off; even the default option of two rotations can provoke this, so this is the maximum practical setting.
Placing the Ferris Wheel at a point in the park where guests have a good view will raise the excitement rating slightly, when done correctly.
In RollerCoaster Tycoon 3, all peeps get off and enter/exit the ride at the exact same time no matter where the peep is.
