Could anyone please advise me how to get from Heathrow Terminal 3 to Cambridge. Should I take the tube at Heathrow to King's Cross and then Train to Cambridge. If yes, please tell the details for so doing? Thank you (I prefer train/tube to coach because I can see a bit of UK's transport). Google map advises me to take Heathrow Express to Paddington, then change for tube to King's Cross and then train to Cambridge, is that advisable for someone carrying a luggage?
