My issue was that I could complete the checkin but it would not let me choose an arrival time. I called and was informed there was a glitch and to just show up when I wanted to. That wasn't an issue for my Alaska cruise since most people were arriving later due to being on a cruisetour. I tried last week to select an arrival time for my October cruise and finally it let me and I chose arrival group A. My problem is I then tried for my November Hawaii cruise and there weren't any group A spots available only B & C, I called medallion support and explained I shouldn't be penalized because their application wasn't working and requested they put me in arrival group A which still hasn't happened. The need to be in group A was to be able to reserve sanctuary days. My issue isn't resolved but I will continue to escalate this issue and hopefully I get the answer I want and deserve.
