Hello, I am hoping Jenner will give me his expert opinion on how to get from London Heathrow Airport to Plymouth. My husband and I (seniors) are planning a visit to Plymouth next year before touring the South West. Flights from California usually arrive at Heathrow between 1:30 - 3pm and having already done research on the National Rail website, see that the best way seems to be the bus to Reading and then the train to Plymouth. But, I cannot find where the actual bus stop is at Heathrow. We need to know if anyone has done this trip and can tell us how to get from the International Terminal to the bus stop, then to the train station at Reading, lugging four suitcases! Thank you.
