Two recommendations: One) Get a rental car if you can, it makes everything a lot quicker. Two) If you aren't renting a car, request a preferred building. Even when you are in the farthest building from the food court I personally do not think it is a long walk by any means, but others disagree, so just throwing in those tidbits in case your one of them.
Besides that you will LOVE it there! This is hands down, my favorite resort at WDW. I've been to the GF, Poly, all the All Stars, all the mods (except for Coronado, no desire to ever go there), etc. and this is still my favorite. Taking walks at night, wtaching the little geckos and lizards running along the paths, relaxing in the hammocks, visiting the birds on the little island in the middle of the lake....It's heavenly! The bright colors just scream CHEERFUL and you wind up in a very cheerful mood no matter what, even if it's raining, bleak, a hurricane... lol This is just a wonderful resort, I've been there several times, and have never had a rude CM here. Obviously some have had bad experiences, which holds true for all resorts (heck, our GF trip is now amusingly deemed "the Trip from Hell") though. The room size is great, particularly for 2 people.

The food court is my favorite of all the food courts, though Shutters is a waste, don't bother eating at that restaurant! The food is average, and overpriced. I still have NO idea why they through that restaurant into the CBR but they did. *shrugs* At least your now warned about that though.

The bicycle rentals, private lake, boat rentals, etc. make relaxing at the resort wonderful all day! There are more pools at this resort than at any other WDW resort, so it's always easy to find a quiet pool. I've never been to the CBR in the down season, only in June or July, and thats when it's supposedly the busiest. I never noticed. It's always felt like my family and I were the only ones there, with a few others. The food court is where I see the most people, and the main pool, but if you want to get away from it all seek out one of the many quiet pools. If your lucky you might get some ducks that will visit with you in the quiet pool and they make great photo ops! (We got a ton with a little family of ducks! It was heavenly and hilarious!) If you have any questions about the CBR feel free to PM me b/c I'm pretty familiar with it's areas, the different rooms and buildings, etc. Have a good one!
