To answer the OP. There is an internal shuttle(bus) that goes between all 5 bus stops of both resorts. Sometimes the boats go between the 2 docks (not so much this year though) and you'll wait longer for the boat than just walking it if you even fit on the boat since it's coming to/from springs.
I'm not sure if there is still the golf cart shuttle between the 2 pool areas (is the POR main pool finished and opened now?) Also I'm not sure if there is a special shuttle other than the bus for the POFQ dining hall rennovation....
It's a fairly short walk, but i'm lazy and it's one of the reasons I want the little POFQ resort when I stay on property.
