Can you use Entertainment coupon #10009123 and combine it with AMEX #5125601. This combination gave me the best rate for picking up at the WDW Care Care Center and dropping off at MCO. Our rental dates are Oct 13-24. Will there be a problem at the counter using two different codes that need identification (coupon + AMEX card)? I have used Priceless and Entertainment together without a problem, but only had to show coupon.
