We arrive in London on Saturday night, and fly on to our next destination Sunday evening at 5pm. We already are booked at a hotel near LHR. We will be passing through London on our way out of Europe for another few days.
My question is this: If we take an early Sunday morning tour (9am or 10am) of the studios (arrive via Uber or cab), and leave by 1:00pm to get back to the hotel to collect luggage and get to the airport for our flight, is this too chaotic? I figure we need to be to the airport by 3pm.
