The LVC is easy to find. Best way to travel is by train, it's on a 10-15 minute walk from the station. Also the night train stops every hour in Leiden. Though parking is also not a big issue. On a ten minute walk you'll find a big, (relatively) cheap parking. from both the trainstation and parking you'll find a route description down here.

Haagweg parking is big, enough place for everybody to park. It's opened 24 hours a day, till 02:00 AM small busses will bring you to the center for FREE! The mini busses are parked at the entrance of the parking. Just tell the driver where you want to go, and he'll drop you right in front of the LVC! Isn't that great??? :-) You'll have to be in before 02:00 PM anyway, because the door closes at that time. But if you prefer to walk it's also a short walk:
