Terrific cruise on a terrific ship. I'll only list the low points and the high points I noticed that were different on the Caribbean Princess compared to other Princess ships and/or cruises.
Low point: Embarkation photo with no background. Didn't want a photo with someone else's arm and the port warehouse in my photo.
High point: Caribe Cafe (at the rear of the Horizon Court). Varied, special meals each night - Oktoberfest, Sushi, Caribe, etc. Another dining option with good food. No additional fee and many people took advantage of this casual dining option.
