I've stayed at POFQ - twice and just got back from staying at CBR. Love them both. We have been at Disney over MLK weekend, so parks are crowded, there is usually a cheer competition, and we expect general chaos.
FQ - small, less walking to get to the main building. The pool is awesome (my son loves it!) My husband and I love the bar area and as a family of 3 would grab dessert and a drink and relax in the evening, they have some fun family games available. They only have a quick service, so food variety is limited. The single bus stop is a HUGE plus. When were were at POFQ we only shared buses with POR occasionally. This is great when trying to get to and from the parks. We are rope drop people, so there were usually lines for the buses each morning, but people were pretty good about being orderly.
CBR - it is big, there are internal buses. We never used them. The Skyliner! Oh, it was fabulous. We went to HS (twice), and EPCOT. It was great not waiting on buses. When we went to AK, we actually were already at HS and just took a bus from there. We also took the Skyliner to AoA to see the Cars area. The main pool was very busy (it was 80 degrees in January!) CBR has better food options and with the Skyliner you could head over the Boardwalk area near EPCOT for even more food options. Our biggest issue was the bus to MK. There are a lot of internal bus stops. We were in Barbados, so the bus started at Martinque, Main building, Barbados, Trinidad, Jamaica and Aruba, then it leaves the property to head to MK. I've read that sometimes they split the resort for the buses, but that wasn't happening when we were there. We like to be on the move. It might not be quicker, but I would consider taking the Skyliner to HS, then the bus to MK. I feel like if I'm moving at least I'm making progress. I should mention we stayed in Barbados 33. It is a preferred room and it was the perfect location for us. Close to the main skyliner station on the same side of the resort as the main building and the bus stop was just outside our building.
So which would I pick next time. Depends on my focus of the trip. This time, it was HS and Rise of the Resistance. POFQ is more laid back, less busy because it isn't as big. My son would take either, both pools have slides. My husband would say POFQ, he "doesn't like people". But yet, we go to Disney. I also don't over plan or make too many dining reservations, so it works. For me, I would probably pick CBR. centrally located and the skyliner just gives you so many options, that don't involve buses. I feel like the Skyliner gives you flexibility, you can change your plans if you want.
