The campfire is available to any WDW Resort guest.
We stayed at CBR last Nov and took my nieces to it one night.
We took the ferry over from the MK and then the internal bus to the campfire site.
There is a small stage that looks like a traveling medicine show wagon on the left side, the screen is in the middle and the campfire is off to the left.
They start the evening with the sing a long and the campfire. Chip and Dale come out into the audience and mingle. Then they show the movie...as the movie plays the campfire slowly dies down. It was an awesome evening and my nieces loved it! The night we were there they were playing a double feature, but the girls didn't even make it half way thru peter pan
Also, back behind the bleacher area are the restrooms as well as the store where you can purchase all of your supplies if you are like us and couldn't bring your own. They had Smores Kits that were plenty for the 4 of us.. I think they were around $ 8.00-10.00. Also hot dogs, drinks, chips etc.
There are pics of the area on the front page at the top "Dis Boards Updates"
and Fort Wilderness Photos - 240 photos added.
(Sorry Photobucket is doing wierd things.. but you get the idea. You can see the corner of the movie screen at the back of the photo.)
