We just got back from POR and we shared buses with POFQ to all parks except for MK. Here were our times -- Once the bus leaves the resort (after it makes all it's stops within the resort) it takes 5 minutes to get to Epcot, 9 to MK & DTD, 10 to DHS, and 16 to AK. So add on maybe a few more minutes from POFQ.
Hope that helps!
