When we stayed at BWV last December, the only place we took a bus to was MK. Walked or boat to Epcot & MGM, drove to AK & DD. We also used the car for grocery shopping & the outlets. I can usually get a deal with National for around $120 for the week (Emerald Club, Disney Club discount, coupon for free day) so it isn't much more than TTC, we need transportation from the airport anyway. The only problem at BWV is it can be difficult to find a spot in self-park in the evening. People park there for Epcot, I noticed most of the cars did not have any WDW resort parking permit. I heard they were having non-resort people park across the street now, so hopefully this year it will be easier.
