This might help:
We will have a car so moving around won't be too much of a problem.
But parking might!!
It is all walkable anyway. Suggest you carry photo ID just in case you are stopped by the Police. This has happened to me twice, once while on the North Fence and once whilst walking around the SW corner. Both times dealt with in a courteous manner and allowed to continue photographing (was going to say shooting but thought better)
