I've discovered another quirk. Today is my platinum booking day for a cruise. I logged in just after midnight to book activities. I could see everything I wanted, but the system would not allow me to book. Tried logging out and back in, different browser, phone instead of computer - no luck. Tried again this morning - same result. Then I decided to complete my online check-in. Lo and behold, after I did that I could book all my activities! Fortunately I got everything I wanted, but this new requirement is going to add a level of frustration. Previously, if I wanted to try to book a cabana, I have occasionally been able to grab one right at midnight on my booking day. Now it's going to involve the added complication of who can complete their check-in the fastest. I guess it's fair if everyone has to do it, but I still don't like it. At midnight, all I want to do is grab my activities and go to bed. Now we have all the online check-in screens to go through first.
