Carnival Sunshine receives mixed reviews from guests. Many praise the friendly and helpful staff, fun activities, and affordable pricing. However, there are consistent complaints about overcrowding, food quality, and some issues with cabin cleanliness and ship maintenance. Entertainment and excursions are generally enjoyed, but some guests found the entertainment lacking or repetitive. The ship's layout and atmosphere can feel congested, especially around pools and public areas. Overall, the cruise offers good value for the price, but improvements are needed in food, space management, and some specialty services.
