The first of the stylish Solstice-class ships, the 2,850-passenger Celebrity Solstice was a game changer for the line when it launched in 2008. The top deck is home to a half-acre of real grass, where you can walk barefoot, enjoy a picnic, and play lawn games. Inside, you'll find many intimate specialty dining venues, an impressive modern art collection, and plenty of tastefully designed spaces where you can hang out and feel away from the crowd — despite being on a large ship.
