What experiences have folks had of private tours of Churchill's home, Chartwell? We are staying in London and thinking of engaging a company called "With Locals" that claims to offer a knowledgeable driver/guide, with a pick-up point at a rail station south of London and a five-hour personal tour to Chartwell and back to the rail station. In six self-guided trips to the UK over the past decade, previously have not tried a privately guided motor tour.
We're experienced with underground and rail travel in and around London and outlying areas, but haven't figured out a convenient way to get from London to Chartwell. A private tour looks pricey for two people, but it includes admission into Chartwell and seems more pleasant than alternatives. But, does "With Locals" deliver what it promises ... a reliable, knowledgeable driver/guide?
Also, do I need check that the company carries the appropriate liability insurance for its business of conveying travelers, or is this a non-issue?
