We always stay IN the park itself - at Apgar. No, there's no electric but there is a dump station. Do you have a generator?

I would love to stay in the park but have concerns with truck and trailer length for sites. I do not have a genset as of yet and not being able to run air conditioner is an issue if warm as majority of family members are "sturdy" and do not tolerate heat well.
