Here is the info from allearsnet.com:
The campfire program is open to all WDW resort guests. It generally begins around 7 p.m. during the fall/winter season and 8 p.m. after the time changes in April through the summer. It is held near the Meadow Trading Post in the campfire area. The program begins with a sing-along led by a Disney CM and a marshmallow roast around two campfire rings. You may bring your own marshmallows or buy them at the Chuckwagon (roasting sticks and marshmallows are $2). You may also buy pizza, hot dogs, candy, nachos, juice, popcorn, sodas, coffee, beer and other refreshments at the Chuckwagon. While this is going on, Chip and Dale make an appearance to visit with guests and sign autographs. The sing-along lasts about 40 minutes. Next, one or two Disney animated features, depending upon the season, are shown on a large outdoor screen. Seating is available in bleachers or on benches. There is also plenty of room to lay out a quilt or blanket. The movie schedule is posted at all comfort stations. In the event of rain, the sing-along is still held on the porch of the Meadow Trading Post.
The movie list is posted on the Dis camping board as soon as someone gets it.
Hope this helps!
