We have stayed at both, and liked each for different reasons.
CBR- We liked that the food court, gift shops, and pool, were all together. We did not like the pool, as much. Smaller slide, and too broken up. You cannot see the kids, from one spot. The bus service was pretty decent. usually quick, but often crowded. We were in Martiniuqe 26, which is a great location. If we had been in an area farther from the big pool, and food court, I think we would have been disapointed. The sit-down restaurant Shutters, was very good.
CSR- We also had a great location 2 minutes, from pool, and 2 minutes to bus. The bus service was awsome. Never crowded, and very quick. fewer bus stops, made it much quicker getting our of the resort. We liked the pool much better there. My kids were 5, and 2 at the time. I could sit between the kiddie pool, and the big pool, and see both of them. At CBR the kiddie pool was off by itself, and You could not see the entire big pool. The pool had a very nice bar, snack shop. We were there in May, and the pools, and that snack shop closed early (8:00 if I remember right). Made it a pain, with a refillable mug, because we were as far away from the food court, as you could get.
We only ate at the food courts, once each trip. Both were just Okay.
Any other questions just ask. You will recieve many opinions, I'm sure.
For our next trip, we will prob. pick CSR. With the Martinique rooms, being preferred, and more $$, we don't like the idea of being further away from everything.
