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.
As repaying the loan isn't needed to complete this scenario, players should definitely take out the maximum loan, as $2000 isn't enough to undertake serious construction. A small roller coaster (Hardwood works excellently) and a non-coaster tracked ride would be a great start, and would take serious players all the way to the entrepreneur goal. Accessing the Tycoon goal would however requie park expansion, and precautious expansion at that.
Two other solid tips for this scenario would involve shutting out the option for janitors to water gardens, and to consider deletion of the whole scenery for an easy $17,000.
