Quick question. Flying down to LHR T5 (from MAN) in the summer. The staying over in the Heathrow Marriot Hotel, then the following day going to T3 for a flight to SFO.
There are 4 passengers, so for transfer from T5 to hotel, would it be cheaper to get a taxi? Would that be a black cab and are they easy to pick up? (Instead of the 'hotel hoppa').
Also, for the following day, would you advise getting a taxi from the hotel to T3? Or is it possible to walk?
The taxis can be quite expensive. If you want cheap, get the HEX from T5 to Heathrow Central (free), make your way upstairs and jump on the 285 bus at stance 21 at Heathrow Central Bus Station - busses every 10 minutes from five past the hour onwards. This is a free journey taking only a few minutes. Just ask the driver to let you off at the Marriot.
You could also get the 285 for the return trip. It will take you a couple of minutes from the Central Bus Station to T3. Its quite a walk from the hotel to T3 and the bus is free.
