Were having a slightly different issue with the web site. We were notified that one of our waitlisted shore excursions is now available. I logged on with relative ease, went to my booked cruises page, found the April cruise, selected shore excursions, saw that the waitlisted one had been added to my cart, which I thought was remarkably efficient for HAL. I selected the checkout option, filled in all the info, using the credit card I have always used for HAL purchases, and got a message that said "There was a problem processing this order. Please review your name on card, credit card number, and expiration date - then submit your order again. Still not working? Please contact your payment provider using the number on the back of your card." So I reviewed and tried again...same message. I eventually tried four different credit cards on two different browsers (Chrome & Edge) and got the same message. My husband logged on and was able to make the purchase.
Then this morning, I got another email saying a different shore excursion was now available, so I logged in and repeated everything I did the day before and got the same message. My husband then tried (Firefox) and now he's getting the error messages on all his credit cards! I can't call HAL because nobody works on the weekends (seriously???) so now I have to wait until Monday morning to call and get this done, and the waitlist is time-limited. According to the CC companies, there is no reason AT ALL that these credit cards won't process. I've used several over the last few days with no issues. I am beyond frustrated.
