BLT like CR has Mickey Mouse - he is all over the place - for some reason other choose not to see him.
so my first choice would be BLT - even the lake view - instead of the theme park view - you might get lucky and get to your left at MK view - otherwise you might get a view of Epcot fireworks.
You can walk to the MK. Boat to WL/VWL and FW. monorail to Polyn, GF, Epcot and MK.
BWV and BCV you can walk or boat to EPcot and DHS. plus you can eat at or just visit BC, YC, BWI, Dolphin and Swan. You can only swim at SALB if you are staying at BCV. they use to allow BWV to swim too - but they did away with that policy several years ago. It is only if the main pool at BWV (the one with clown) is down that they allow pool hopping to BCV. BWV has night time entertainment.
you are more likey to get OKW or SSR - both are great for DD. you can walk, boat or bus to DD. bus transportation to everything else. These are different from the other DVC resorts. they are more like communities than resorts. they are set up like condos. probably more like windsor hills than the other dvc resorts.
AKV is a great place to stay - to visit the animals. for visiting the parks like something a little closer to the action. it is bus transportation to everywhere.
VWL is a MK resort just not on the monorail - it is the only MK resort to have bus service to MK and Epcot. plus boat service to the Mk.
Now you don't get the great views of the MK here like you do at BLT - but it is just as magical.
so don't be disappointed no matter what you get - think you might enjoy the DVC resorts. Plus never having to drive anywhere is a treat. You can order grocery so you don't have to pay Disney prices.
Wishing for you to get the DVC resort you want.
here a place to look around and see what appeals to you
