Hope the weather isn't too bad for you.
It would be a shame to get up to the castle and not see the view - especially of the Marine Court flats in St Leonards that were built to look like the superstructure of an ocean liner.
Still if it's misty and murky, then wandering round the old town you may get the feeling that the press gang will jump out of a passageway and take you off to sea!
Hope you all have a great day in a really interesting area
