It shouldn't be more than a 10-15 minute walk unless you have children with you. Mine like to look for lizzards, snakes and frogs along the way, so we need to make a few stops to ooooh and Ahhhhh all the critters and crawlers they find.
It's one of my favorite walks at Disney-so peaceful and it's usually followed by a fantastic dinner at Yachtsman Steak House.
We had dinner at Cape May on our first night in December. The walk from BWV is easy, as people have mentioned. Then we headed to Epcot for Illuminations. It was a perfect beginning for our trip!
