Paul, as I intend to stay at Hotel Draper: 17, 42, 3.1415926535, 2.7182818, 2007 (I hope these are enough numbers - if not, just tell me, I can provide more ...) ;-)

Paul, a few years ago it was 48 pounds for the cab - single fare. Makes 96 pounds for the return trip.
Up to 4 passengers per cab (gets very cramped then), i.e. 12 pounds per person single, 24 return.
With 3 passengers it's 16 pounds single, 32 return.

(plus price increasements over the last few years ...)

I don't know the prices for hire cars ...
