Can you walk around the castle grounds for free? Not sure id want to pay to go in (broke emoticon). That would be nice enough to walk around the castle, but does anyone know of anything else that might interest her? Im not sure she has encountered dickens yet so not desperately interested in that. We will be travelling by train, will there be any decent swing parks? possibly along the medway? DD will be happy "if theres a swing park" otherwise im not sure its worth the trek
