I will be visiting southern England at the end of September to cheer my sister on her swimming of the Channel. There will be a two week window of when the swim might happen and the actual swim could be many hours. We will greet her upon her return to Dover.
I would like to stay close but not Dover proper. I enjoy exploring history, nature, gardens, and architecture. I plan to do a few days in London too. I need recommendations on a home base near Dover and public transport and a property in London that would have similar flexibility.
