I made a reservation for January using the Entertainment Book's Free Two Class Upgrade coupon - upgraded from Mid-size to Full-size. I'm an Emerald Club member but it's stating that I have to use Counter Service. Do you really have to go to the counter or can you just go to the Emeral Reserve - Full Size aisle, pick up the car and give the coupon to the attendant when exiting? I hate to stop at the counter - seems to defeat the benefit of Emerald Club Membership. Thanks.
