The water slide on the Adventure and other Voyager class ships is for smaller children, not teens. The slide is open from 3pm to 5pm on port days, and from 11am to 3pm on sea days. It's not open on boarding day. The teen club is for teens from 13 to 19. The Voyager class ships have a children area called ADVENTURE OCEAN
which is over 2,500 sq.ft. Click HERE
