Are you traveling with an electric vehicle - car, golf cart or other vehicle type?  Many Best Parks in America affiliates are now offering charging services for these special vehicles.  Be sure to check with the park to be sure they can provide this service.  Most parks offering charging are charging a nominal fee for 4 hours or more of charging.  Many also allow use of the park's facilities during the charging period.  Another 21st Century Service coming at Best Parks in America.
