The Entertainment program is a coupon book, not a code and it is good for $20, not 20%. You have to use the numbers off the coupon when you make the reservation and present the coupon when you pick up the car. All the Entertainment books have the Alamo coupons, no matter what city they are for. There is also a coupon for $25 off which is only good for picking up the car on Sunday, Monday or Tuesday and there is another which is good anyday for $15 off.
