Hello,
We will be arriving by plane to London Heathrow on a Saturday in June (4 pm) and planning to take a train to Paddington station near where we will be staying. Should I go ahead and purchase tickets in advance for both this and our return to Heathrow, or can we purchase when we arrive? Are cost savings significant for buying these in advance, as for trains throughout the country? I'm only hesitant as there is always the concern of a flight delay and potential for missing a train. Also, how much time would you allow between landing and getting to the train for reservation time?
