Hi! I have done this before (many times, she said, thoroughly embarrassing herself) but I still ALWAYS get confused.
When arriving at Terminal 3 from the USA, the tfl.gov.uk trip planner tells me I have to take the Heathrow Express to Paddington Rail Station, get out and walk to the Paddington tube station, and continue on to the Baker Street stop (where I am staying).
But I remember getting the tube directly from Heathrow, without the annoying transfer and the added cost of the Heathrow Express. The tube map shows the Piccadilly line goes to all terminals... and it does so as a "regular" train, yes? I would have to pay fare for Zone 6, it looks like, but otherwise I remember just taking a normal train that wasn't an "Express."
So what I am not remembering? Is tfl.gov.uk not telling me about the "regular" tube option because they want my sweet, sweet tourist money? Or am I just plain wrong?
Leaving tomorrow. Thanks you guys! :-)
