Yes train is free to tempelton stn,

Richmond nearby if you like although nothing to do except shop here. Although better shops at Oakridge Mall which is easy to get to in about 15 mins without change of train.

and if you do not wish to venture far, The Fairmont Hotel is on top of intl terminal with great restaurant and fabulous view too. You can then go outside as little park with trail right in front of intl terminal.

unfortunately, depending on day of week the AC intl lounge can get pretty crowded so bit noisy for my taste.

All minor matters, have s great trip
