Yeah,
PBR is the furthest (sp?) from the parks by path...and probably by boat. If you go to PBR first (recommend taking the boat from CW,) then HRH, you will be coming back towards CW and its an easy stroll (from HRH) to the boats or the path at CW to RPR.
Remember, you can take the boats to and from any hotel to CW but the boats don't run between the hotels.
