Well, we have stayed at CBR and are to be staying at PO-FQ in October.
We liked CBR, but it was HUGE and a walk to get anywhere, as we were in the Barbados section. The theming was very nice, and the grounds and rooms nicely maintained. We didn't like the food court, though, and the pool was on the small side. There are 7 bus stops and the busses do stop at all of them before heading to the parks. The check in area and the food court/shops/ main pool are not in the same building, but are on opposite sides of the resort. The sitdown restaurant was nice, but only serves dinner. Our favorite 2 things were the Banana Cabana pool bar, and the room size (bigger than the other resorts).
PO-FQ is a smaller resort, and no room is very far from the bus stop or the main building. In the mornings and the evenings, there are separate busses from this resort, which only has one stop. It shares amenities with PO-R, which means your selection of 7 or 8 pools, 2 of which are themed, 2 food courts and a sitdown restaurant at PO-R that serves both breakfast and dinner. You have the boat to DTD in the evenings, as well. The rooms are smaller, however, and there is no sitdown restaurant actually IN PO-FQ.
Really, it is all a matter of taste and preference, and comes down to theming and logistics.
Good luck in your decision!
