Last year, I bought several $500 Princess gift cards on Princess website during a promotion. In January, I used them to pay for 2 cruises. After paying for the 1st cruise, I still had one unused $500 card, and another $500 card with $200 unused balance. So, I called to pay payment on my 2nd cruise, the balance was $950. I planned to use the unused $500 card, used card with remaining balance of $200, and charge $250 with my credit card. The Princess agent told me Princess system can only take one type of payment, either pay all with gift cards or all with credit card. Since my remaining gift cards total only $700, which is not enough to pay my final payment balance of $950, then I will not be able to use my gift cards; I need to pay the entire $950 with my credit card. So now I am stuck with the two gift cards that I can only use them if I happen to have purchase of $750 or less,
