The BWV is one of our favorites. If you hadn't thought of it, it is very convenient to order groceries from an online service to be delivered to you. It seems to be a long walk to grab a bite, especially a snack or breakfast so these are handy items to have in the room. Also, don't forget some DVDs for any down time.
We prefer walking to Epcot and DS, as the boats seem to take forever. The walk to DS is particularly good for an energetic child who needs to burn some steam!!
The Boardwalk at night is beautiful and romantic and the street performers are very entertaining. You will love it there! Have a great trip.
