Instructions
Locate the two "very important people" that you are supposed to impress. These VIPs are labeled as such and are wandering around your park with the other visitors. When you locate a VIP, click on him or her to bring up that person's informational box. Keep both informational boxes on screen so that you always know where the VIP is located.
Pay attention to what the VIPs want to see in your park. This is randomly generated and how you respond to their needs affects your ability to beat the scenario. If the VIPs say that they want a fast ride, for example, use the "Build a Ride" toolbar to add a fast ride to your park.
Click on each VIP and drag them over into the line for the ride you built. Drag them directly over the ride's line and release them. This will drop them into the line. The VIPs will get on the ride.
Let the VIP get off the ride. Make any suggested adjustments to your ride based on the informational boxes for the VIPs. Keep clicking on them and dragging them into the line for the ride. They will go on the ride over and over again. When each VIP is sufficiently impressed, you will have completed "La La Land."
