Don't be intimidated because this is the last scenario. Although not easy, this is not an extremely difficult park and the main difficulty is the setting of your terrain. This is one of the few scenarios in the game where guests can have a long walk to reach the rides. However, this shouldn't be a big problem as there is also a Chairlift. You might want to consider building roller coasters on top of the rock and smaller gentle and thrill rides in the desert. This can be quite a hard park, however, there is a lot that can be done here, and the guest goal is incredibly low for the time given.
