This is the hardest scenario so far and potentially the hardest scenario in the original game (maybe only second to Rainbow Valley). But it shouldn't be hard if you know what you're doing and if you plan your park properly and reasonably. At the beginning you should focus on building some thrill and gentle rides and a small roller coaster (preferably a cheap one such as the Steel Mini). Keep on slowly expanding your infrastructure in so far as you research new rides. You should keep the strategy used for earlier scenarios, but not forgetting to build compact and underground whenever possible.
