MSC Seaside receives mixed reviews from guests. Many praise the ship's beautiful design, excellent entertainment, and some standout staff members. However, there are consistent complaints about small cabins, repetitive and bland food, inconsistent service, crowded areas, and issues with excursions and port times. Pricing is seen as reasonable by some but others feel nickel-and-dimed by extra charges. The overall experience is enjoyable for many, but several guests compare it unfavorably to other cruise lines, especially regarding food and service.
