Since the Oosterdam was my first cruise, I can't compare it to other lines/ships. BUT let me say that I had the BEST time on that ship!!! I was rooming with a friend, and we were both part of a group cruise for handbell ringing (if that hadn't been a draw, I don't know if I'd have ever gotten around to cruising... SCARY THOUGHT!!).
Flew into San Diego that morning, and got to the port in plenty of time (via pretty inexpensive taxi ride). Did the online pre-registration but there was still a long line. Still, it moved pretty fast. Separate line for suite guests.
Had to hand over luggage, but most people kept one 'carry with' bag with essentials. We were in our room by 1:30 as I recall, and had a nice lunch on the Lido before that. Our whole week was very calm seas, which was nice. The week before it was rough going all the way. Go figure.
