We have stayed 4 times now, always in cabins in 2500; I honestly don't remember the numbers, but as you entered the loop, they were down the left side, on the left side of the loop. (if that makes sense LOL)
We *loved* our stay there, every time! It's so very quiet and peaceful; we would often see deer and bunnies out the windows in the early morning. I know that 2500 loop looks like it should be noisy on paper, but we never experienced anything louder than the laughter from our neighbors as they were grilling their hot dogs! And speaking of neighbors, everyone at FW is just so friendly! We love to stay there because as we would come back from the bus stop, everyone who was out on their deck would wave, and holler "hi!" - and it's so relaxed that you just get to know people easily and quickly!
Honestly, the only "con" about the Cabins (for me personally) is that you (almost always) have to take at least 2 buses to get anywhere (especially outside of FW)* but it's a small price to pay for the space, the peace and quiet, the friendly neighbors and the sheer beauty of the place.
The Cabins were "refreshed" a couple of years ago, and while you still have a full-size fridge, and dishwasher, there is a smaller cooktop, and the microwave also is a convection stove. We don't typically cook; we mostly use the fridge to store beverages and the microwave for popcorn, and our breakfasts at the Cabins are typically cereal and milk, so the kitchen is probably a bit wasted on us, but we do love the amount of space you get.
I'm sure you will have a great time, no matter which cabin you are in - be sure to take a tour around the campsites to see how everyone has decorated for Christmas!
*my personal mobility device will fold to fit on a golf cart, but we prefer to let Disney do the driving, so it's buses for us! (and the occasional boat ride!)
