Maybe I'm too much of a thrillseeker, but the two Skycoasters I've ridden (PKI & PKD) bored me. To me, they felt like nothing more than overgrown swingsets. Granted, I haven't been on the 300-footer in Kissimmee, but I can't imagine it's *too* much different.
Now, that 200 foot bungee jump I did was thrilling. It is a much different feeling to fall straight down than it is to swing on an arc.
Just my opinion....
