I am not the OP but have been following because we too are looking into rides from LHR to our hotel, Park Plaza County Hall. It is near Waterloo. I have been looking into all options. Am interested in what might be the fastest and then also price. If we took the tube, about how long might it take (We get into LHR at 1030)? What tube lines/stations should we be using? If we paid for a car service how long would that take at that hour?
Also, does anyone know how long after we get off the plane to allow for getting through everything and getting our luggage? We will be in T3.
Thanks for all your help!
FYI- OP, looks like we come in the day before you but are sailing on a different ship. We will take the train to Southampton and when disembarking ship use International Friends (we have used them before) for an excursion with drop off at our LHR hotel.
