Some of us have cruised Oceania and most recently Regent.
On Oceania, you need to show you card constantly even to dine.
On Regent, they had many substandard interactions with crew. We even had to report our cabin number to be seating in Compass Rose.

Crystal always had multiple choices of music, dance, lectures, art....at any time.
