"Princess Cruises offers a Halloween weekend getaway onboard Caribbean Princess that’s just five nights in duration, with two unbeatable ports—Grand Turk, and Princess Cays, the line’s private island in the Bahamas. A highlight of this seasonal sailing can be sitting in the ship’s piazza, watching festive passengers promenade their inventive costumes for spooky onboard revelry—a Princess tradition dating back to the days of the original “Love Boat” series."
