Less so with 3 bags per person, but I take your point.

Just to clarify, taxis do not have access to Terminal 1 (like if you were coming from Paris?), or no taxi driver would take a fare from the Sheraton to T1 (which I fully understand)?

And to be clear myself: I am looking for airport-area strategies that minimize taking escalators and elevators (when they work) and squeezing luggage through bollards, etc.
