We are planning a day trip from London to Hampton Court next month.
We might take a train at 09:36 (so, off peak). We are 4 adults and 3 children, so the best rate we can use is a 22.60GBP off-peak day return.
How long in advance do we have to be at the station to get the tickets and get that train?
How should I ask at the booth for the GroupSave card? Do we have to pay extgra for the card?
