This is my first and last sailing for princess cruises. First and foremost, this ship is not following any COVID protocol. Many passengers were chatting about various members of family getting COVID on board and most were not self-reporting. Case in point, there is COVID spreading on every sailing and you'll have a good chance of getting it on board.
I'll start with the good:
The cabins and food are decent overall. The Discovery is new so it seems a bit more modern in interior design at least.
Interior cabin was fine. Bathroom smelled funky when I boarded though.
