I am planning to pay for the remaining balance of the DCL cruise with Target Disney Gift Cards to take advantage of the 5% savings. Costco Travel confirmed it is not a problem. Aside from the monies getting returned to the original gift card IF something happens, is there any other reason not to use gift cards? I can't use my AMEX but other credit cards have some sort of benefit but I can't think of a valid scenario where it would really help given all of the exclusions.
