Usually there are people out there that will help you and push you to the spirit gate to get checked in. They will not let you just park there so you would have to push your person inside then go park the car and then push them to the spirit checkin, if the workers are not there to help you
You can be dropped off in front of terminal but whomever is dropping you off cannot leave car there and take you to spirit counters
