I have a reservation with National. I have joined the Emerald Club and have made a ressie for a midsize on the Emerald Aisle. I combined two codes and a coupon for a good price. I got the coupon via Mousesavers thru the Vaction Outlet link (for use by anyone). The print out of my reservation states that the level of service is "COUNTER". I read two conflicting accounts - one says that I can go directly to the EA and present the coupon after I select a car. The other says I need to go inside to the counter first. I do know that if you have a coupon and are NOT an Emerald Club member that you have to take the coupon to the counter if you made a Quick Rent ressie. Anyone have any experience with EA and coupons?
