I will start with the bad, and end on the positive.
BAD: Food quality was not good. I would say it was adequate to slightly sub-par.
This was my first Alaska cruise, and the last time I did another cruise was in 1994, so I may have had unrealistic expectations. But on that cruise, I was sincerely impressed by the quality of the food, and the diversity of options available.
All good. The service in the room was exceptional. They must have come in 3 times a day to clean or make the bed, etc. Truly remarkable. The room always smelled clean, and we always had clean linens and towels. Stateroom was small, but that is to be expected. The view from the stateroom was excellent and the deck was regularly cleaned. HOWEVER, we only ordered room service once, and it was not good. This seemed to be consistent with the food quality as a whole on the cruise, so nothing too remarkable there.
