What's are the best/reasonable options for a family of 4 (2 adults, 2 kids) to travel from Chelsea / Kensington area to LHR? We have a 7am departure to Rome on Alitalia. We are travelling fairly light.. I expect to have about 4 carry-on duffel bags, 4 small backpacks, and 1 large check-in bag.
It seems that public transportation may be limited for early departures. Any recommendations for car services / shuttles / other options?
