I am flying from the US to Heathrow arriving at 6;45 am Thursday morning May 30th either in T3. I realize this could be a busy time. I will not have checked bags. I'm trying to guesstimate the time it will take to get through Passport Control and to the Central Bus Station. I am on my way to Cambridge. The bus ticket I have is flexible, but I want to book a tour in Cambridge that same day and want to make sure I can make it with some time to spare.
You all have been so helpful with all my questions about this trip.
Thanks in advance.
