We just disembarked from the Fantasia two weeks ago. First of all, the Fantasia class ships (Splendida, Divina, Preziosa, and Fantasia) have always been our favorites. All four are exactly the same, traditional and intimate.
The current YC director and chief butler are great as is the YC restaurant manager. You'll have a wonderful cruise. The internal lift in the YC goes from deck 14 (spa), the two cabin decks 15 and 16, and up to the lido deck 18.
