Just got back from CBR and it was a really nice resort. We were in Martinique and it's definitely worth paying a little extra for this because it's close to the food court and bus stops. The rooms are a good size and well equipped and ours was very well maintained during the stay (the cleaner really took a pride in her work, and even left some of those little towel animals people go on about). The pools were clean and pleasant - we tended to use the "local" martinique pool rather than the central one because it was quieter (often we had it all to ourselves). My only 2 gripes: 1) you had to get to breakfast early otherwise the queues got very long and tedious and the staff were noticeably surlier when under pressure, and 2) we always seemed to just miss the bus we wanted to catch by a few seconds (despite running for it!) - this was uncanny, maybe we were simply unlucky but it happened every time.
We have only ever stayed in All Star Music before, so thought we'd try a moderate resort. I would say, all in all, it was just about worth the extra money, but it was a close thing! Hope you have a great stay wherever you end up.
