If forum remembers, I asked a question on how to get from Heathrow Terminal 5 to Victoria Coach Station
I ended up staying in Terminal 5 and exiting to coaches
I was able to buy a ticket inside terminal from a live person who told me the schedules
Walked out door and found the spot. Bus was already waiting
Made a stop at Central Bus Station before continuing.
Traffic was not much of a problem Some of the journey was pretty. Some Fall colors, some.
And end of journey was a bit of sightseeing.
