We did that last December, and if I remember correctly, we had to catch a bus to the Wilderness Lodge or to another stop near the front of the campground. Then, we caught a bus to Downtown Disney, where we got a bus to the BCV. It sounds complicated, but it really wasn't that bad, and the bus drivers were very helpful. They're the ones who told us what to do.
BTW, the campfire makes a nice, quiet evening. And, of course, the s'mores are yummy. Have fun! And, say "hi" to the BCV for me. Do you happen to be a DVC member, too? I forgot to look under your name before I started this message.
