So with the 3 new ships to be added to the DCL fleet between 2021-2023, the grand slam will become a thing of the past. Now you will need to hit all 7 ships, which requires a new name for the feat. My suggestion: Pulling a Snow White.

So I went back and looked - Magic five times, Wonder two times, Fantasy two times and the Dream five times. Have 3 upcoming trips one on the Wonder, one on the Dream and one on the Magic. I started cruising with Disney in 2008.
