Be aware that the the temp lot mentioned above that is across from the front door area is no longer a temp lot. It has been turned into valet parking and when I was there in May, they had barriers up preventing others from entering it. If doing nothing but checking in, they will allow you to park temporarily right past the front door entrance unless others have already temporarily parked in the few spaces there.
If you are doing online check-in and prefer avoiding check-in at the resort, then suggest the following if you do not have your room number yet when you arrive and your intent is to just go directly to a park while waiting for your room text. The under-building parking lot has one entrance and exit on the south wing of the resort which entrance is well-before the front door area as you drive in. There will be a stop sign and a sign saying parking to the right and as you look to the right, you will see the opening in the building to the under-building parking. Turn right at the stop sign, go into the under-building lot and turn left. Drive until you see the Timon elevator on the left. Park as close as you can to that elevator. Go up that elevator to the second floor, come out of the elevator and go to the hallway and turn left. Walk to the next exit sign which is a door to the outside on the left, which takes you directly to the bus station. Later when you get your room number, you can return from park, retrieve car and drive to parking area closer to your room.
