I am arriving into London with my parents (aged 60 and 65) at 0715 Hrs. I have a same day connecting flight at 16.30 Hrs. We will be on London transit for the first time and wish to see London while we are there.
Now, I expect to clear immigrations in an hour and travel to Central London in another hour by the underground tube. This means i'll be at Piccadilly latest by 10am. I will have to depart Central London by 13.30hrs in order to reach Heathrow in time for my next flight.
So, basically I have 3.5 hours time in Central London and I plan to make the most out of it. Please thow in your suggestions!!
I am not comtemplating Windsor as an option.
