I see a lot of great reviews about CBR. It has a laid back tropical feel to it. The biggest complaint they get is that it's large and spread out. That's an issue for some, but not for others. Did you request a room in a closer building? Or book a preferred room to ensure it's closer? The only ones that are definitely furthest away are the pirate rooms. CBR also has one of the higher rated Mod level pools and it has a kids splash area that the other mods don't.
On the other hand French Quarter gets good reviews because it's much more compact so walking to the pool or main building is easier. It does only have one bus stop which can mean easier access and less time sitting on the bus, but can also mean bigger crowds where you might potentially have to wait until another bus comes along. It also has the boat to DTD which is a really nice little cruise if you have plans to be in that area, and you can pool share with Port Orleans Riverside.
Both resorts have their own pro's and con's so take a look at pictures of the resort grounds and room pictures and pick the one that appeals to you the most. They are both nice resorts and you aren't likely to regret either decision. If you decide to change the process is easy and you just need to call.
