Thanks for the feedback guys!
As far as the supports on Shangaan, I think I may leave those as is.
Intimidator 305 and
Skyrush only have two large supports on their respective lifts, I have four. My first reaction was that Shangaan looked unsupported but that was my reaction when I look at these coasters too.
Those coasters also have much thicker track on the lift hill which I do as well. You'll notice that I've put B&M track under the giga track to make it look a little thicker. That extra track also goes straight into the ground at a steep angle like I-305 and Leviathan. As a side-note, I originally used Intimain Impulse track for this and it looked awesome but it was really glitchy when the train went up the lift (similar to those awful Phatage catwalks) so I switched to B&M track and I'm pretty happy with the results.
Regarding the bridge between Hasta Fiesta and Western Adventures... you caught me. There is an underground path from inside the Skyride station in Hasta Fiesta to the underground exit path of Runaway Mine (The mine train in Western Adventure). When the park is done, the paths will form a circle around the river but for now it does appear to have a very badly designed path system. I've made sure that peeps don't feel "lost or stuck" and even when the park is completed, the underground tunnel will remain where it is.
As far as Flat rides go, the flat ride to coaster ratio isn't too bad for most of the park, but you're right about Forbidden Jungle, it's very coaster-heavy. I just went through and checked each area's coaster to flat ride ratio.
The entrance area has 4 non-coaster rides (Wave Swinger, Monster, All American Carousel and Swan Boats) to one coaster (Firecracker).
Hasta Fiesta has 6 non-coaster rides (Swiss Sky Ride, Monterrey Mixer, Tiujana Tumbler, Moreado Manor, Los Coches and Rio Grande Expedition) to 2 coasters (El Diablo and Rattler).
Vampire Forest has 2 non coaster rides (Transylvania Twist and Nightmare Manor) to one coaster ride (Vampire).
Western Adventure has 12 non-coaster rides (Trailblazer, Tumbleweed, Gunslinger, Rodeo, Swiss Sky Ride, Sunset Railway, Route 66, Round Up, Haybaler, Buzzsaw, Exposition Theater and the all new "Twister") to 5 coasters (Runaway Mine, Inferno, Sidewinder, Outlaw and Nightmare Mine).
Forbidden Jungle has 6 non-coaster rides (Swiss Sky Ride, Sunset Railway, Bongo Boogey, Abonsam Cavern, Senegal Spin and the all new, "Magic Carpets") to 5 coasters (Abassi, Monsoon, Kilimanjaro's Fury, Python and Shangaan).
I'm planning on including all of the flat rides that I have but the park is so huge that some areas may be a little light on them so I don't ever have to have two of the same ride. As I mentioned above, I have added two new rides...
