We love CBR. We just got back a week ago from our second stay. Here is my review:

I agree with other posters that CBR like all resorts will have its positive and negative reviews. But our 11 nights there were fantastic as was our first trip there back in 2006.
We had great bus service the whole time, but I will say the route can take up to 15 minutes from the first stop (which was usually us in Jamaica) to the last one. Normally it took us closer to 10 minutes but if we had a
scooter that needed loading or there were other busses in front of us loading or unloading lots of guests and or scooters, that could increase the time. But once out of the resort, its centrally located and we got to where we needed to go pretty quickly. I found the route to be equal to POR's (if not shorter since POR often shares with POFQ) and shorter than the shared routes of the Epcot and MK resorts. I find that bussing evens out. But we had no problems either of our stays with the busses.
As for the location of your building, we really enjoyed Jamaica and would gladly stay in Aruba. But our first stay was in Barbados and that section was great too. The only section that is really sort of "far out" is the one with pirate rooms (Trinidad South). To me, any standard location is going to be 5-7 minutes on average tops. Next time, I may not even request a section because we'd be happy anywhere within the resort.
I booked a bounceback offer so we are set to stay at CBR again in October. We can't wait!
I have learned to just realize that we can't all like the same things and that WDW resorts have thousands of rooms with so many guests and that any resort can and will have some dissatisfied customers. But I do think that overal, Disney works hard to keep their guests happy. If you have any issues with any resort you stay at, take up in person at the front desk!
As for other hotel sites like Tripadvisor, pretty much all Disney resorts rank low. Not everyone is thrilled with the price they pay and I think many people think "onsite" means you will be very near all the parks. Disboards is different because it is more for seasoned Disney lovers and people who may be taking their first trip, but they are doing their research and know more what they getting! Disney is expensive and has set high standards for themselves, which makes their guests expectations very high!
If CBR appeals to you, go ahead and stick with it. Because the minute you change, you'll start seeing bad reviews on the new resort you choose!
