Our ships boast a sea of vacation possibilities for every guest. Like the chance to learn Italian, salsa dancing（萨尔萨舞）, or the recipe（食谱） for a perfect martini（马提尼酒）. To conquer the rock climbing wall and ice skate on the equator. Or slow things down with a hot stone massage（按摩）and duty-free designer shopping. See, do and learn more at sea than you ever thought possible.
North Star
The exclusive North Star promises to heighten your worldview. Simply step into the North Star's closed, jewel-shaped capsule and gently climb over 300 feet above sea level. Take in breathtaking views of the ocean, the ship, and the exciting destinations that we visit.
Royal Caribbean
Royal Caribbean is teaming up with World Wildlife Fund to save our oceans and protect sea life. Join us in making a difference by symbolically adopting a sea turtle or get involved with numerous other activities both on board and ashore, like the Walk for Sea Turtles. Together we can turn the tide.
SeaPlex
SeaPlex is not only the largest indoor active space at sea, but also the most modern and creative. By day, experience a circus school and flying trapeze（高空秋千）, as well as a full-size regulation(正规的) basketball court. By night, the first-ever bumper car（碰碰车） and roller skating offerings at sea will deliver thrills, with music provided by a floating DJ booth that hovers above the activity happening below.
Rock Climbing
Rise to the occasion and take on our signature rock climbing wall. From beginners to speed climbers, everyone can enjoy an unparalleled view from 40 feet above deck. Included in your fare, no reservation required.
