I would NOT recommend CBR with small children. I find that resort is always overcrowded and everything is far. No elevators so keep that in mind if you have strollers. I know people love the pool at CBR but honestly how much time are you going to spend there? Food court area is nothing great, actually think of all the moderate it is the worst. People rave because the kids meals come in sand buckets with shovel! We had lots of issues with the buses at CBR where we never did at the other moderates.
Also since you are used to Deluxe, I think CBR will be very disappointing. I would say CSR is more like a deluxe but I haven't stayed at either of POR since the remodel!
