We have stayed at CBR twice and had wonderful trips! The new rooms are nice and the beds are comfy. We have stayed in the preferred section and also in Jamaica so our walk to the food court was not bad at all. It is a pretty resort with a tropical beach feel, and it is so pretty at night! Our bus experience was fine and we will stay there again I'm sure. The only down side to CBR that I don't like is the check in process. You check in at a totally separate house and then have to take another bus over to the main house or to your room. At other resorts, you just get off at the main house and then walk straight to your room. So anyway...that part is annoying, but it by far won't ruin your trip
If I were you...since you are pretty much just sleeping at your resort of choice, I would save the 1300.00 and stay at CBR. You will most likely be just as comfy there as you would at Poly for the night. Have a great trip!
