Carnival Sunshine receives mixed reviews from guests. Many praise the friendly and helpful staff, fun entertainment, and affordable pricing. However, there are consistent complaints about overcrowding, mediocre food quality, and issues with ship cleanliness and cabin maintenance. Entertainment and activities are generally enjoyed, but some found them lacking or repetitive. The ship's layout and public spaces often feel congested, and some guests were disappointed with the value and specialty services. Excursions and ports are generally well-received, though some found port information lacking. Overall, Carnival Sunshine offers a fun and budget-friendly cruise, but improvements are needed in food, cleanliness, and crowd management.
