Well, considering I'm staying at BWV in December and WL in January, I don't know that I'm the best one to ask, lol!
However, a couple questions that may clarify things in your mind . . .
You mention DHS. Are you going for the Osborn Lights? There have been times when the transportation leaving the studios after the lights is really crowded. It's nice to be able to walk back to your resort at night.
You mention looking at decorations. Fort Wilderness has some great decorations on the campsites and it's very easy to get there from WL - not so easy from BWV (although it can be done). Visiting other resorts would be about the same from either (although I'd give a slight edge to BWV as you can walk to DHS and catch a bus to any resort).
As far as the rooms themselves, the studio at BWV will have a slightly larger fridge and a microwave. WL will have a small fridge and no microwave. BWV will have one queen bed and a sofa bed that comes in handy when you don't want to sit on a bed (like waiting for someone to finish getting ready). WL will have two queen beds. The bathrooms are laid out very similar, so that's not a deciding factor.
I like both resorts (I stayed at BWV in January and WL in May this year as well) and you really can't make a wrong choice between them. Think seriously about where you will be spending your time and about which theme appeals to you the most, and one of them should rise to the top of your list.
