I figured out how to get my Emerald Card applied....I just "rebooked" the reservation and cancelled the other.
As far as the Contract/Coupon numbers. When I printed out the Entertainment coupon, there is a Contract ID of 5066914 and the Coupon ID of 10009123. When I put those numbers in, the price is somewhat higher. I'm just concerned if I can use the Priceless Contract ID as the entertainment coupon says "not to be combined with other discounts or promotions."
