We have stayed at both and love both. Here are the pluses for WL, courtyard view: (inner courtyard, I have pic's but don't know how to post).
View of Pool and geyser
Theming to the max, actually feel like you have stepped into an old Park Service Lodge
Everything under one roof (great in inclement weather)
Contemporary:
Huge rooms
Monorail access
Walk to Magic Kingdom
4th floor concourse has lots of shops
Both are great but if you need the room for 5 (CR has a daybed) and larger room size/bathroom size, I'd say go with the CR. Being the first stop from the Magic Kingdom on the Monorail is great. The SOuth wing is undergoing refurbishment now, depending on when you go you may luck up and get a "new" room.

Either way you won't go wrong.
