You start with a decent park, but you should still lower the entrance fee to $20 for now. People aren't as poor as in the previous scenarios, so you can raise it again after expanding the park.
Set your research to Thrill Rides, since you start with a decent selection of roller coasters, and add some gentle rides to the mix later.
Start by hiring additional staff, each 1 mechanic and handyman by far isn't enough to care for your rides. Now reduce the Ferris Wheel to 1 rotation and increase the maximum allowed people on the Spiral Slide to 5 (if you decide to keep it). Reduce the maximum waiting time on the Steeplechase rides to 10 seconds, since they are synchronized and so one without passengers can create unnecessary waiting times. Since a breakdown can cause the same problem, have a mechanic patrol exclusively around those four rides.After stalls are placed, start building rides around the stations of the Steeplechase coasters. If you build compact and remove the slide, you can add 2 or 3 more coasters in this corner. Also, build a roller coaster near the entrance to welcome thrill-seeking guests properly. Time is of the essence, since you have only 2 years to complete this scenario, so you might consider relying on some pre-made rides and of course marketing campaigns.
