I need to go from Southampton to Heathrow Airport, UK. Is it true that I need to purchase National Express tickets in advance? My cruise docks at Ocean Terminal. Is there a way to catch Nation Express right there at the terminal? Thanks.
You will have to take a taxi from the dock to the Bus Terminal. It would be best to buy your coach ticket on line though the buses are frequent so you could wait & buy it at the bus station. Google "Southampton to Heathrow" for more info.
National Express have discounted fares for advance boooking. Sometimes you can get very cheap fares.
