Hi, we just returned for POFQ, and the buses are good but very frustrating also. There was no rhyme or reason to if they went to POR or just did pofq. But here is my experience. Get the very first bus each morning, 8 am. That bus is not so full, and more times than not it only did one resort at 8 am. If you miss that bus, at least at pofq you are doomed, the next two or three buses will be totally packed full with standing room only. And you will not get to the park and be first you will be way in the back of the crowds. We did first bus every morning and was first in line at the bridge. Go to the bridge side you want for that day because it is hard to cross over in the crowds, so if you want splash mountain go to the left, if you want space go to the right. Peter Pan either, but the castle is closed so it is a long walk either way, one thru adventure land, the other the right side of the castle and around thru fantasyland.
On the way home again check where the bus is, they kept changing ours, one day at 14, then 18 then we had to take the POR bus, no rhyme or reason for these changes. Try to go out when the crowds are in park, like right before fireworks, or during the parade, if they are just getting over than wait an hour and then leave otherwise not only will you not get a seat, you will be stepped on, foot rolled over by carriages and little kids or parent banging you. It was not to bad if you could manage not to go at park closing, parades or wishes.
