The Ruby Princess receives generally positive reviews for its service, ship cleanliness, and memorable itineraries, especially to Alaska, Hawaii, and the Panama Canal. Many guests praise the friendly and accommodating crew, enjoyable excursions, and relaxing atmosphere. However, there are notable criticisms regarding declining food quality, repetitive or lackluster entertainment, crowded conditions, and some issues with cabin comfort and ship maintenance. Pricing and value are seen as fair by some but questioned by others due to extra charges and perceived cost-cutting. Internet connectivity and specialty services receive mixed feedback. Overall, the Ruby Princess is recommended by many, especially for first-time cruisers and families, but repeat cruisers note a decline in standards compared to previous years.
