absolutely BWV!
you can just stroll to EPCOT for dinner (ferry or walk to both EPCOT & MGM), there is quite a bit going on at the BW in the eve: arcade games (basketball, water ballon shooting, throwing lobster in pot), surrey bikes, shops, hair braiding, "street performers" (magician, sword/fire-eater, etc), restaurants (ESPN, big river, spoodles ~ which also has a pizza take-out window) jellyrolls (dueling piano bar), atlantic dance hall. you can see (& hear) parts of Illuminations from the BW, or go over to the bridge (directly past a beautiful gazebo) for a better view.
during the day, the main (clown) pool can get crowded (& noisy); we prefer the "quiet pool" to read a book, & just soak up some sun during the day
i love getting an ice cream, or picking up a delish baked good at the bakery
our 2nd choice would be SSR. getting a view of DTD would be great, but even without it's a beautiful resort with a very relaxed elegant feel. you could walk or boat across to DTD (inc PI & the marketplace
)
of the other 2 (just MHO): OKW has the larger rooms, but we found it rather isolated. very pretty & relaxing.
BCV is beautiful also (with geat access to EPCOT & MGM), just very noisy with a lot of kidlets IMHO (great if you're traveling with little ones, but not our choice for "adult only" trips).
