We have stayed at the POFQ 3 times and the POP once.
The bus service at POFQ is FAR superior to that at the POP in our experience.
The best thing about the POFQ is that, with the exception of the DTD runs, it is the first place to pick up and the first to drop off. (When sharing with the POR) We never had long waits for buses and we almost never had to stand.
One of the reasons we probably would not choose the POP again is the bus service. In the mornings there were long lines for the parks (especially the EE park) even an hour before that park was due to open) We had to wait for 3 buses to come, fill up and leave before we could get on one to the MK. We just BARELY made it for the park opening.
When we stayed for WISHES we took our time leaving the park and spent almost 45 minutes strolling through the shops on main street. When we got to the Queue for the bus, iThe POP line streched all the way back down the bus stop pavilion (it was the farthest one down too!) We waited for more than an hour to get a bus, then we were packed like sardines, for the LONG ride back to the resort.
I know that this is not allways the case from reading other peoples reports, but this was our experience. (we were at the POP mid week during the 2nd full week of November)
Hope this helps!
