Well the best place to stay is subjective to ones tastes!
I love OKW, it's my favorite resort. I love the room (bigger than most resorts), I love the lush landscaping, the main pool area, and the tropical feel of it! Some people complain about it's lack of Disney theming and the way the resort is spread out, both which I prefer. CLose to Epcot & TL.
However, sometimes, usually when we bring someone new to Disney it is pretty cool to stay at AK and get a savanah view. The animals feeding just below your villa is pretty spectacular. Jambo rather than Kidani has a more impressive lobby and its where Boma and Jiko are located. Close to AK.
With that said, BLT though ultra modern in design (not my favorite) does have a view (if you can get it) of the fireworks at MK which would be worth doing! Personally, not a big fan of highrise buildings! CLose to MK.
I guess for you it depends on what theme and what type of accomodations you and your family might want and the amount of points your friends are willing/able to let you have. You don't need a car, the buses, boats etc. work at all of them!
Good luck with your decision!
