Personally, I'd have a massive jump line with progressively bigger jumps, a few airbags, with a unique, diverse rail line to the side, as well as one rail which runs the entire length of the park. Of course, a detachable t-bar which does not stop if a gaper falls on it on each side is essential. Indoor facilities would include trampolines (with trampoline skis), water ramps, and foam pit with a foam pit ramp. Oh and let's not forget hot tubs all along the side of the park. Can't ask for much more than that.
