I just ran it as a point crawl and the PCs were just hacking through thick jungle and camping at night (for night encounters). I only drew either a location or a camp site as needed.
Are every point of interested is supposed to be done in order, or should we decide how to place them? I don't see somewhere if the connections between them is written
I wrote it to followed in numerical order, but there's probably some flexibility with the order of areas. There is also a seperate download for a free map, made by someone else. Hope this helps!
