I think you could do this.
After the HDDR, take an Orange Bus to the 600/800 loop bus stop, and take the bridge over to the campfire area.
I believe that once Daylight Savings Time ends, the campfire program begins at 7, with the movie starting around 7:40. From November to March, they play two movies on Friday and Saturday night, so you could definitely see the second movie.
