"Basic vanilla and chocolate soft serve for your complimentary ice cream, versus the variety of ice cream on offer at the Oceanview Cafe."
I believe that this varies ship to ship. I found that Odessey of the Seas had a similar hard ice cream set up in the Windjammer to that of Celebrity. Although the ice cream was not as good. On the other hand, Harmony of the Seas didn't have hard ice cream in the Windjammer all the time. I had to purchase ice cream on the Boardwalk.
