Hi! Congrats on your upcoming marriage.
We have stayed at CBR four times. Each time in Martinique. The distance to the foodcourt/marina/store is very short no matter which building in Martinique. We did not find it noisy nor did we find the quiet pool crowded. We have always gone during school vacations as well.
I will say that if we stayed again, we wanted to try Aruba because it is across the lake and there is a bridge to walk over. But it is dark at night, there are lights but it is not as well lit as the pathways. This would not bother us, but for some it might.
Good luck in planning and just a note, when we went we could not "book" a specific island, only make a request. (Each time we got Martinique though - I called the room controller one day before the trip and made sure)
