Visiting Hampton Court Flower Show in July. Plan to catch the 111 bus from Heathrow to the flower show . Return journey will be train from Hampton Court Station to Waterloo and then tube from the Waterloo tube station to Liverpool St Station. Thereafter we will catch a train to north of England.
Not sure whether we should just pay by cash. I believe we will be travelling at peak time so bus should be only £2.40 but we are struggling to work out cost of return journey. Will return trip be classed as a single trip if we pay by cash ie. £5.70 peak rate Hampton Court to Liverpool St. or will we have to pay separately for the train part and the underground Waterloo to Liverpool St part?ie. £5.70 plus £4.70 peak. Not sure if it is worth the bother of buying an oyster card and having to get a refund at end. If we decide on an oyster card how much should we put on it to cover the journeys?
