I'm attending a christening in May in Orpington with dh and dd (19 months by then). Thought it might be nicer to stay in a B&B a bit further out - what's Sevenoaks and the surrounding area like? Is it a nice place to stay for a long weekend? Any hotels/B&Bs that anyone could recommend? Nothing flash/expensive - just somewhere we could go for a nice walk to shops with toddler in tow.
