You exchange the coupons for vouchers at citywalk guest services. You cant tell the voucher is from a coupon, its the same as the one you buy, so yes, you can use all 7 at once. When you exchange them, they have you wite down your name and address. They dont ask for ID of any kind or for your Entertainment card. I turned in multiple coupons several times during the week. Remember when you go to the restaurant to tell the server you are using the voucher, you get a different menu.
