Whoever designed the Disney parking lots was a great person. When are arrive, just follow the line of cars and then do what the attendant tells you to do. Why? Because you will be parked in a space that allows you to easily open your doors (both sides) after you pull in. The spaces are angled very well. Once you get yourself together at your car, walk forward, toward the park and then up the next aisle where there will be no vehicle traffic, just foot traffic. There will be other vehicles entered and parking but all that will be behind you. Once out at a main aisle going towards the park, there will be tram stops. If you want a tram, you can wait and board one or, you can just walk up on the pedestrian walkway to the front of the park.
As stated, once you get up to the main aisle going towards the park (where you can pick up a tram), write down, note or take a picture of the aisle marker that is on the pavement. That is your marker for your exact row for when you leave.
When you do leave, just follow the exit signs out of the park and you'll be home free.
I do suggest that you park where the attendants want you to park and not try and get "something closer". It's just not worth it.
