Exactly.
If you drive your car out to the front entrance of the Fort, then take a left just past the bus depot, then follow that driveway towards a guard arm. The guard arm will raise automatically for you to exit the registered guest lot. Then drive toward the back corner of the Overflow lot and Kenny will be there toward the main road. If you want to drive your vehicle back to your campsite, one of you will have to exit the parking go on the main road and enter through the guard shack again.
The person driving the golf cart back will need to proceed through the "red poles" with the golf cart to enter the registered guest lot, then drive the cart back to the campsite.
