One big advantage is that with MK right next door, you have easy connections to any resort on property. That is a big plus if you've planned dinners at some of the resort restaurants, or if you have a dining reservation in World Showcase at Epcot (if you take the BC bus, you can enter through International Gateway and be closer to your restaurant). You can either take the monorail around and then walk to the resort bus stops, or just walk from CR to the resort bus stops. Personally, I don't think there's a whole lot of difference in the walking distance either way. If you do the monorail route, be sure to allow about 30 minutes for the monorail and then another 30 to catch and ride a resort bus (walking will save you 15-20 minutes, in my experience). There is also a boat at the marina behind CR that will take you to FW and WL.
