A truly impressive building program introduced one of these gigantic Voyager-class ships per year over a five-year period. With their rock-climbing walls, ice-skating rinks, in-line skating tracks, miniature golf, and multiple dining venues, they are destinations in their own right. Sports enthusiasts will be thrilled with nonstop daytime action.

The unusual horizontal, multiple-deck promenade-atriums on Voyager-class vessels can stage some of the pageantry for which Royal Caribbean is noted. Fringed with boutiques, bars, and even coffee shops, the mall-like expanses set the stage for evening parades and events, as well as simply spots to kick back for some people-watching.

Other public rooms are equally dramatic. Though it's considered to be three separate dining rooms, the triple-deck height of the single space is stunning. These ships not only carry a lot of people, but carry them well. Space is abundant, and crowding is seldom an issue.
