Haven't stayed at CBR (maybe next time), but I've stayed at the other moderates, and our favorite, by far, was Port Orleans French Quarter. It's a smaller resort, so the rooms are all relatively close to the food court and bus stop. It was the quietest of the resorts for us, maybe because of fewer people. Its nice being on the Sassagoula, so you can take the boat to DTD.
But honestly, we didn't dislike any of the moderated we've tried. Riverside and Coronado were also quite lovely in their own ways.
