If we're arriving from the United States and want to purchase FareSaver tickets for the train, must we change change terminals to the domestic terminal (to go to 7-11 or PharmaSave)?
I'm pretty sure my wife would make us take a cab if we had to change terminals to buy these things.
It's one big terminal. End-to-end (which you'll need to do) is a 5 minute interior walk, tops. Then you'll have to retrace most of it to get to the station
. Leave the wife and bags at the foot of the escalator to the train.
You won't get a cab from one end to the other, not without seriously upsetting the cabbie. Might learn some foreign curses though.
