We absolutely love the CR. Had a great time there last year. Given we had a 3 year old, it was great to be able to walk to and from MK. The CR is no bigger than any of the other resorts, all depends where your room is. We were in a Garden Wing and did not mind the walk. They are doing a lot of work both with the adjacent rumored DVC construction and the lobby and concourse renovations. Generally these don't bother me, but may be for you to consider. We were hoping to stay at the Poly next trip, but I think it is just going to be too much right now especially given my son is no longer free. My wife would also like to stay at GF sometime, which is of no interest to me unless we can do Concierge or a suite. I think the fact that you are staying on the monorail is the most important part. Other than that, don't sweat it. Just pick one based on your gut feeling and enjoy. It will be awesome either way....
