I see no reason why you couldn't drive your car to BW - stop at the gate, you should have a car pass from CSR, tell the guard you are going to visit the Boardwalk/have dinner or whatever... Park your car (or valet) go down and enjoy the Boardwalk - walk on over to Epcot watch Illuminations then afterwards stroll around the Boardwalk before you head back to CSR. By the way, I agree with Ducklite- have a beverage in the Bellevue Lounge - just off the lobby inside the resort. You might even decide to walk on over to BC/YC and see what all they have to offer - maybe an ice cream at Beaches & Cream - maybe a mouth watering filet at the Yachtsman Steakhouse - maybe a beverage at The Crew's Cup Lounge. You won't be sorry, your bank account may be sorry - because after you visit, you'll just have to stay at one of these great resorts on your next trip. Have fun!
