If you have any specific questions, please feel free to post them and someone will try to get you an answer :-)
The Sky is beautiful. My only advice for this ship is ask for the foam pads for the beds. It took me two days to finally ask the cabin steward because the bed was so hard. (From what I heard, I wasn't the only one who thought the same.) We also found the staff on Sky very warm and friendly. An elegant ship.
