Many people have made videos about the Carnival Sunshine. These are a few of the best.
Enjoy the informative Carnival Sunshine Pros and Cons Review by "Mr and Mrs Traveler". Learn the good and the bad from a whole group of people who went on the cruise. They like the multi-tiered Serenity Deck for adults-only, uncrowded areas on decks 6 and 7, and extra breakfast spots. One "con" is that some areas are overcrowded.
Cruise Critic offers a couple of unique videos about the Carnival Sunshine. One is a review of restaurants where you can eat free on the ship. The other is about can't-miss spots on board (Havana Bar, Bonsai Sushi, the large Serenity area for adults, Aqua Park, and Sky Course ropes course).
Maluna Travel made a Carnival Sunshine cruise review video. See all they did on a trip to the Bahamas. They had never cruised before. Includes scenes from their balcony stateroom, the pool area, casino, meals, spa, shows, and Half Moon Cay.
Joe Somebody offers a video about boarding the Carnival Sunshine. He and his wife flew to the port and bought transfers from the airport to the cruise terminal. Priority check-in was worthwhile. They liked their cabin with balcony. Good tips.
