Well I've never stayed at CBR, but I very much enjoyed my stay at Coronado Springs. The rooms were clean & the atmosphere relaxing. If you like Mexican/American Southwest architecture, you'll love it.
Others may disagree here, but I found the resort to have a bit more of an adult feeling to it, probably owing to the convention business. I didn't see many kids there when I visited, and no characters were running around.
Nonetheless, the resort has a great pool, a health club, and the Pepper Market food court, which was nice and convenient. I do recommend you stay in the Casitas or Cabanos sections though, as they are closer to the lobby & food court.
One side perk of Coronado Spring is the efficient bus transportation. Since most people are away at a convention, the buses here are rarely crowded, and (at least during the time I stayed), did not share with any other resort, which significantly improves the wait times. Hope this helps!
