My friend & I were there at the end of October. What we did was park the car in the main lot and walked up to check-in (about 2:00pm). Our room was ready but we wanted to eat lunch, so we headed to Big River Grill. Then after lunch, we went back to the parking lot and I drove the car up the entrance and dropped her off with the luggage. Then I reparked the car and walked up to the entrance and we took our luggage to the room. Then we went out for groceries, I dropped her off at the entrance with the groceries and parked the car. I got alot of exercise that day! We are both able bodied adults so it wasn't a problem. Now, when my mom was alive, we always used bell services, it was too much for her to drag the luggage to the room.
At check-out, we took our luggage to the RAC desk and checked it and took our carryons to the car.
