We stayed at POFQ the first week in March, 3+ weeks ago.
We were quite surprised when a bus we got on at POFQ then proceeded to make all the POR stops, so I asked the bus driver about it. The driver told me that after 11 a.m., POFQ shares buses with POR.
I don't know if this is always the case or if it was just going on the week we were there. But if it's always the case, then the midday post-resort-pool/nap trip you've factored into your analysis should take this into account.
I can't attest to what happens on the return trip, because POFQ is the first stop and I never bothered to check if there were still people on the bus after I got off.
BTW, I often stay at AKL, and one of the big transportation pluses of staying there is that a bus to DAK comes extremely often and the ride is perhaps 7 or 8 minutes, max. We often go to DAK as our 2nd park--even when it's our first park!
