We are traveling by public transport from either Bath or Chippenham on September 12 to Heathrow Terminal 3 , for 1 PM flight on 13th. Trying to figure out least amount of transfers and best places to stay without risk of delays. Have booked Raddison Conference center near terminals... Looking at other options with less transfers... Bus from Reading Station, staying in Slough etc.
Doe anyone have experience or clear knowledge?
Thanks for your consideration!!
