Playing with the rates at YVR this weekend and I've discovered a 3-day rate is CHEAPER than the two days I need, thanks to a lower rate and the weekend day free coupon. What I'd like to do is get my aisle pick then drop it either at South Terminal or Downtown, both of which will be closed as of Saturday afternoon (I'm dropping around 7 PM) and will therefore charge me through to Monday which costs less than dropping at YVR Sat night.

Does anyone know if either has a drop box for after hours returns? I'm thinking downtown might even be easier thanks to the Canada Line and I'm worried South Terminal may be shut if there are no flights in the evening.
