I agree with PP that if you keep preferred and end up in Martinique, its a bit of a walk to the Skyliner. However, I think it depends on how often you'll be using the Skyliner to know if that's even an issue. For us, we used the pool and visited the food court more often than we needed to ride the Skyliner, so if we had to compromise on one, we'd rather have the hike to the Skyliner. Martinique is also close to Riviera, so you always have the option to use that Skyliner station, or even visit their QS.
IMO, there's not one ideal location at CBR that's close to everything, but preferred Barbados is about the best you can get. So I would keep preferred.
