As best I can remember, there are a few parking lots for DHS cast. The one I used to use was next to costuming. You go into the "main" guest gate and follow the cars headed toward the normal parking lot. At one point, you have a CM waving you to go to the right. Flash your ID and he'll let you go left. Follow that curve around and you are in Cast Parking. If I had a map, I could probably draw it out for you. There are also parking garages near the Animation building we used for a short period of time, but I think normally those are reserved. No clue on Typhoon. Never went there.
