Depending on our respective commuting times I figured we could make a rendez-vous off our trains one morning. If the times don't work it's just possible I could persuade the AMT coffee lounge to be a drop-off point as I've been faithfully buying my morning cappuccino there for a year! I usually arrive at Euston around 8:46 but could make that later or (with the grumbles of all night-owls confronted with early rising) earlier.
