My wife and I are hoping to take a top shelf personal Beatles tour in Liverpool that will last about four hours and cost three or four hundred pounds.
I'm curious what others think is an appropriate gratuity. If it were a tour bus with forty other people I'd probably tip about 5 pounds, but given the high cost and exclusivity, what would be a proper amount in this instance? I want to be appreciative, but not taken advantage or either.
FWIW, the tour will be conducted by the owner of the business and chauffeured by her driver.
