My shipmate and I booked this cruise after the MSC Seashore TA cruise was suddenly cancelled. In the end this was a godsend as the Sky Princess turned out to be absolutely the best possible voyage.
Boarding the ship was a breeze in Southampton - took half an hour to drop baggage, get Covid tested, and pick up Medallion.
The ship is gorgeous! Very tasteful and no water slides, carousels etc. My room was changed from deck 5 to deck 10 and turned out to be a room with a queen plus two upper bunks - very spacious. There were only 1100 passengers on board a ship that can carry 3660 passengers. So there was never waiting for anything. At times there were more wait staff in the World Fresh Market (cafeteria) than there were passengers.
