The Library Bar

Found on: Carnival Vista 

Carnival, a cruise line known for its “Fun Ships,” isn’t necessarily the right one for someone seeking solitude, but even passengers who like to party might want to chill once in a while. The solution? The Library Bar on this 3,936-passenger ship, which combines comfortable seating for reading, playing chess, or doing crossword puzzles with a wine bar — keeps some of the fun on tap (literally, as there are self-serve wine dispensers for an added fee).
