You are going to get all kinds of answers on this one. I have stayed at both POFQ and POR and CBR, so I will give my opinion and you can do with it what you may.
Both CBR and POR are large resorts and have Preferred Rooms (but they cost more). This area is where I feel CBR beats POR, CBR has an internal shuttle that will move you from "Island to Island", but at POR you will be walking it. This is not a problem at POFQ as it is a small resort.
Transportation: We found the bus service better at CBR for transportation to the parks. But that is just our opinion. So, POFQ rates higher here for us, as it is a smaller resort and only one bus stop, so while you may not always make it on the first bus, there is always one shortly behind. So my ranking for Transportation: 1st: POFQ, 2nd: CBR, 3rd: POR
Pools: We like the Main pool at CBR the best. POFQ is geared more towards younger children, as the slide is for the less adventurous and the CBR slide is for the older kids! POR pool, we found to be dirty, water was really cloudy and always full of debris, but this could be because it is surrounded by trees and such, where CBR and POFQ are not. While at POR we spent alot of time at the quiet pool in the mansion area. Ranking: 1st: CBR, 2nd: POFQ, 3rd: POR.
Food Court: Hands down POR has the Best Mod. Food Court!!! They have the best selection for adults and kids meals!!! CBR comes in a close 2nd, as they offer kids meals in sand buckets which can be used on the CBR beach. We just didn't eat too much at POFQ food court the time we stayed in the past, but OMG!!! The Benieghs are to die for!!!!! Ranking: 1st: POR, 2nd: tie CBR and POFQ
Rooms: This is a personal issue for everyone, we love the size of CBR's rooms, they are a bit bigger than POFQ and POR, but they only have full size beds and well we like our space when we sleep in this family. So, the queen size beds at POR and POFQ are desireable. But we also have been known to travel with twin size air mattresses for the DDs, so we make due with that at CBR.
We like all 3 resorts, but for different reasons. We probably won't stay at POR again, we prefer POFQ and walk over to POR for the food court. CBR is our favorite, but POFQ is a very close 2nd!!! We have stayed at CBR the most, but this time we are trying POFQ again. I am hoping we are going to love it!!! The 1st time we tried there, it was raining the whole time, it was Dec. and cold, so the kids didn't really get to enjoy the pool, and we are really hoping for a pleasurable time!!! Good luck choosing, it is a hard choice!
