I am sorry if this post appears monumentally ignorant. It is just that we don't drive.

Various family members are coming to see us over Christmas. We are going away to SFO. They want to leave their car somewhere, so I need to find a ling term car park, here in London near King's Cross, not at LHR. I have looked at a nearby NCP car park, but it seems to offer season tickets on the basis that you enter and exit every day.

Doers anyone know of a car park in central London which would (doubtless for a non-small fee) allow you to leave a car there securely for eight days or so.

Very many thanks
