I opted for the valet service with the coupon I got on their website this was only $8 more than economy. In all honesty my experience was perfect. I dropped off my car, registered at the desk, and was driven to the terminal in roughly a 10 minute span. All very early (6 am). Then when I returned around 12 am I called when my plane landed picked up my luggage and waited 5 minutes or less for the shuttle to pick me up. When I was dropped off at the office my bill was handled quickly and professionally. I was in my car driving away within 30 minutes of my plane landing. And they give aeroplan miles!
