We have stayed at the CBR 8 times so it's pretty obvious that we love the resort. From what I have heard the walks at POR and CBR are about the same. We have stayed in both preferred and non-preferred and our longest walk (from one of the furthest buildings to Old Port Royale) was a little over 7 minutes and that was only because we were behind a very slow moving couple pushing a double stroller. Our walks from the other non-preferred locations were about 5 minutes. My mother who is 78 had no problems getting around the resort.
Each of the resort villages has their own bus stop, quiet pool, beach and laundry facility.
As far as the bus transportation goes, we have never had any issues even though some of our travel dates included Star Wars Weekends, Memorial Day, early to mid-May and early to mid-August. The resort is centrally located so it doesn't take long to get to any Disney destination.
The food court has a nice variety of foods to choose from at breakfast, lunch and dinner. If you want to just grab a bite to go, there are some pre-packaged snacks in the resort store or you can grab something from the grab-n-go station in the food court. I posted pictures of the selection from the store over on the CBR pic thread. You can also request that the servers put your food items on a to-go plate and then ask the cashier for a bag to carry your items out in.
The main pool is awesome! It was redone a few years back and is now zero entry and has two slides. For the younger kids, there's a separate play area just for them near the main pool. Weather permitting, movies are shown in the Old Port Royale courtyard and marshmallow roasts are held on the beach between OPR and the village of Trinidad North.
At night, you can see some of the higher Illuminations fireworks from several spots around the resort. Our favorite spots to see them are on the Martinique beach or from the OPR courtyard.
If you have some extra resort time, I'd suggest that you rent one of the watercraft, a surrey bike or a bicycle from the marina. One of our favorite things to do is take a spin or two around the resort on the bikes.
I have lots of pictures of the resort in my trip report (link is in my signature below) and on the CBR pic thread.
If you think of any specific CBR questions, feel free to ask and I'll try to answer them.
