We do RR a lot and it is not complicated at all. Go early to KP Hole, pay your fee's and look/ask for Captain Bill. He runs a pontoon water taxi service upstream from KP Hole. He only takes cash, have him take you to the "wall" (furthermost spot he takes divers) and ask him to spot out the cool caverns/holes etc., while motoring upstream. Then just take your time drifting down stream, don't fin down stream as you will miss some stuff. Once you hit 500psi or 50 mins bottom time, just poke your head up and see how close you are to KP hole. From the wall to KP Hole, I would say 60-75mins provided you are not fining down stream. Worst case scenario, just poke your head up and have a look-see. Most of all, HAVE FUN!!!
