From Carnival's Website:

Everything the sunlight touches on Carnival Sunshine has been doused with an extra dose of fun. There's plenty to find atop this ship, where you can spend your days being kissed by the warm rays of the sun. Visit the biggest Serenity area ever, featuring three decks, plenty of recliners... and even a waterfall. Carnival WaterWorks, our onboard waterpark, doesn't just deliver the favorites... this one debuted the slick Speedway Splash slide. There's also SportSquare, where you can let your inner champion run free (around the jogging track), traverse SkyCourse high up above, or even engage in a little one-on-one, from ping pong to foosball to giant chess.

When you're on your Carnival Sunshine cruise, step out of the sun and try out some shade (and it's some pretty cool shade, at that). The first thing you'll see is the Sunshine Atrium... and let's just say first impressions count. From there, check out dining options — this ship has everything under the Carnival sun — like Guy's Burger Joint, BlueIguana Cantina, Fahrenheit 555 Steakhouse and JiJi Asian Kitchen. Some of the greatest Carnival bars are here: RedFrog Pub, BlueIguana Tequila Bar, SkyBox Sports Bar and Alchemy Bar... plus the already-classic Havana Bar! You'll enjoy musical revues from Playlist Productions, while Hasbro, The Game Show gets cruisers like you up on stage, competing in larger-than-life family favorites come to life.

When you find yourself between the Carnival Sunshine and some actual sunshine, fun at sea is guaranteed 

What I Love About This Ship:

 This is one of my favorite ships in all the ocean! This ship was rebuilt "Extreme Makeover" style in 2013 and she's gorgeous! All of the best things Carnival does are here: Guy's Burger joint (by celebrity chef Guy Fieri), Blue Iguana Cantina, a wonderful comedy club curated by George Lopez, amazing waterslide + outdoor ropes course, an adults-only Serenity Deck, and much much more. The kids' clubs are Dr Seuss themed and they have programming for tweens and teens too. And it's ALL included in your fare.

The decor on Sunshine is bright and modern. Carnival still has some of the largest staterooms at sea. The ship has a capacity of 3002 passengers so it's moderately sized for a modern cruise ship...not too enormous! This ship is an awesome choice for multi-generational families. The Serenity Spa is gorgeous and features thalassotherapy pools (included in your fare in a Spa category stateroom, or available with a day pass for everyone else.)
