Something I haven't seen people talking about is how the additions of RMC Gwazi and Tigris, and the repainting of Kumba, has really turned the park around. The dead areas are/will be gone (except Rhino Rally of course), and the popular areas are/will be less crowded as a result. And it also seems like Adventure Island is starting to become a great water park with the additions of Colossal Curl, Vanish Point, and the new water slide opening next year.
2020 is the year to be an annual passholder.
