QwertyChouskie, there is very little special about Carnival del Cacao. As far as I know, most of the geometry is the same; only the lighting is changed. Fireworks and lights are available as library nodes and you could easily copy the skybox and ambiant lightmap (spherical harmonics) from Carnival del Cacao. Have you read the documentation? Have you started learning Blender yet? That will take some time, and you might as well learn before trying to jump headfirst into modeling a full scene.
