On my next visit to England, I would like to visit a historic site in the middle of the countryside, about 10 miles (20 minutes drive) from the nearest train station. Without nearby public transport or bike rental, I'll need a taxi (licensed Hackney Carriage).
After about 2.5 - 3 hours, I need to return to the station.
Considering the journey time and the time I spend at the destination, is it usual just to pay for the rides there and back? Or might the taxi driver insist on waiting on site and charge me for the waiting time?
If the taxi does not wait, will the outward and return journeys cost about the same?
(This might be a rather general question how taxi fares work. So far, I've never made a return trip by taxi, so have no experience how this works.)
Thanks in advance for your help.
Edit: Since you've been asking, the place is Hidcote Garden in Gloucestershire. I'll probably go by train from Birmingham to Stratford-upon-Avon, and onwards to Hidcote by taxi. On a previous visit, I took a taxi one way and returned by bus from nearby Mickleton. While researching my trip, I found the bus route has been under review and will be withdrawn soon - it's not clear when, and if at all, the bus service will be running again.
