I think you would generally find things to do at all of the deluxe resorts, so you should be set in that regard. If you are looking for a Christmas-feel, then WL is stunning and very cozy during Christmas season. We are staying CL there in a couple weeks and have read great things about it. You would be close to MK and can boat there if you want. There is a path to FW and we are planning to rent bikes and explore over there.
If you want to see Wishes from your room, Poly has a fabulous view right from the CL longhouse (Hawaii). As posted above, I'm not sure what phase construction will be at, though. Hawaii is newly renovated, so your building would be fine -- just not sure about the main building or surrounding areas.
CL at CR is fabulous too and the view is breathtaking from there too. Only drawback is I'm not sure how much of a Christmas-feel you'd get at CR if that's important to you. But it has a great CL with a great view, walking path to MK, Chef Mickeys, fun arcade.
Have not tried GF main building CL, but I've heard it's top-notch.
BC is my favorite resort, but I'd almost feel sad if it was too cool to swim at that time of year. The pool is awesome, easily our favorite in Disney, just not sure if your weather will cooperate. CL is very cozy there and we have always enjoyed it. You can rent surrey bike and have a pretty ride around the bay -- I'm sure it's gorgeous at Christmas time. You can watch Illuminations without entering Epcot. Of course, it's a short walk into the Epcot countries for some great meals. Very fun and pretty area to stay.
