Is their electricity at the camping site and do they allow campfires at the camping sites?

yes and no

Electrical at every site, but no campfires on individual sites. However there is a campfire/movie night under the stars at the center of the campground almost every night, weather permitted I believe.

Power at every site. You can bring an approved (has to be enclosed with lid) firepit. Quick google search will bring up the pic of approved ones. But they do have the campfire sign along every night.
