RCT2 Rio Carnival help

I'm well into my challenging parks and doing pretty good. But I cleared all my beginner parks and can't seem to get anywhere with this one. I've come back to it a numbr of times and it just seems to be a big mess that I can't seem to make any money with. Any tips or help would be much appreciated!

I take it that's an RCTWW scenario as I havn't seen it in RCT2 or RCT2TT.

I got the RCT2 triple thrill pack so yes I assume it's part of the expansion packs.

I always demolished a bunch of the unnecessary scenary and paths to make money then build a couple of solid attractions that will draw both money and people.

As usual I only play the custom scenario's,as is I've yet to even get started on any scenario's in RCT3 but I did finish the SFOT scenario in RCT2 about a month or two ago.
