Komondor - Even in airports which are connected beyond securoity (so that I can enter one terminal and access the others), I have never seen that many shops available at one time. Admittedly I don't travel in/out or through every airport, but my list includes Philadelphia, Dulles, and Los Angeles. Even adding O'Hare where with some work I can get to most of the terminals, I have never seen that number offered even by a combination of MSCs. San Francisco and Newark often have half a dozen available at once, but each terminal has its own security scan (Terminal A at EWR had three different security entries which connect to different arms of the same terminal and you can't get into one without a ticket for the airline served by that arm). I am either missing something or I am traveling to the wrong airports. If I could do 8 - 10 shops in a few hours inside one airport and not have to worry about mileage from one place to another or getting wet moving from car to each store, I would jump at the chance!
