We fly in to Heathrow and have a 4 hour layover. We have friends that live about 30 minutes from the airport that we would like to see.
Is it practical to leave the secured area and have lunch with them at Terminal 5?
We are traveling on to Rome. When we land in London, will we have to pick up luggage and recheck it, or will it be forwarded to our next flight?
Our concern is timing. We don't want to have to drag our luggage around with us in and out of security.
