There are usually multiple strategies to successfully completing a scenario; these can be discussed on the scenario's discussion page or written down in an existing or additional section of this article.
This scenario isn't as intimidating as it seems, though it is advised that you have your coasters built beforehand. If you're using the computer's prebuilt designs, Stratasphere and Lava Launch work very well. After you have three coasters that meet all the requirements, up through tycoon, advisably, just build stalls and platform rides until you achieve the guests in park requirement. Also, keep in mind that this scenario is rather rainy, so indoor rides are advisable as well. Also, do NOT delete the chairlift because you can NOT repeat NOR rebuild it!
