Sold Out and just going through the process at 0 dark thirty in the morning to book and finding Vikings server slow as a snail is a complaint on every ocean cruise we have taken with them. Our last cruise Midnight Sun was particularly frustrating as by the time I picked and adjusted choices and went to check out. I found two excursions we wanted were Sold Out, did not say that when I selected them. I complained and likened it to being in a grocery store where I had picked up the last item of a particular product and had it in my basket when the manager walked by and said I need that as I have a customer ahead of you who is checking out and wants this item. We really like Viking and have has issues with them and they have come through. But this issue has been totally ignored. Just my 2 cents worth. We still can't wait to get on board.
