For the sake of coming up with some sort of schedule...how much time would you plan to
A: get out out of Heathrow - we'll be flying in from the US, mainly carryon luggage but maybe one checked bag- arrive 10am
B: what would be travel time to get from the airport to near the Tower Bridge (south side of river on Queen Elizabeth Street)
Also, does anyone have a car serice they recommend? There will be 6 of us but not much luggage.
Thanks
