It's called for about 7PM and if you've never been to Ft. Wilderness, it's a little hard to find the campsite it in the dark. The buses don't go directly to the campsite. Make sure you get a map of the place...
I really loved it, but my husband thought it was mostly for kids...
Chip and Dale come and you can take pictures. We had a lady singing while playing her guitar. She sang simple songs that everyone knows, so it's nice because pple all join in. Old McDonald had a farm, B-I-N-G-O (but with PLUTO, instead), a song with the states in the US and pple cheer for their state, some Disney songs, a Happy Birthday song for those whose birthday is that day/week. They also had kids come up and sing "It's a small world after all".
There are two fires going and pple stand around toasting marshmellows, franks, etc... After the singing is over they show a cartoon on a large screen. You can call ahead and find out which cartoon they're showing. I think on the weekends they show two...
When we went, the petting zoo was closed already for the day.
