Dolly Parton is revealing why she missed the announcement of the Night Flight Expedition ride at her Dollywood theme park on Wednesday. In a video message for fans attending the event, the singer said she couldn’t make it in person because she was experiencing health issues. Parton suffered a kidney stone that led to an infection and on doctor’s orders, she stayed home to rest. The country star told fans not to worry and assured that she’s going to be okay. The new Dollywood Night Flight Expedition is inspired by a nighttime voyage through the Great Smoky Mountains in North Carolina.
