If you want to stay over nearby there are some hotels in Chatham and Rochester. They are all a taxi ride away from the wedding venue and you should book in advance - see the taxi page.
We've not had a chance to check the hotels ourselves, but the Holiday Inn is good value and the Bridgewater Manor Hotel looks a bit swanky! Both are about 15 miles from the wedding venue. The Ship and Trades Hotel is a small hotel that looks a bit quirky, it is a little nearer, about 8 miles away.
