I'm trying to book reservations in the main dining room for our March cruise. I was able to book for 3 day of the cruise but then it stopped working. I would add the date and time of the reservation to my cart, then click my cart to check out, but my cart would be empty and say "O items". Then I tried adding to my cart and go directly to "Go to Payment" instead of clicking on "View Cart", but it's the same problem. My cart is empty. I tried logging out of NCL and logging back in. Same problem. I tried using a different web browser, Edge instead of Chrome. Same problem, empty cart. Has anybody ever encountered this issue?
