The 3,082-passenger Crown Princess may be one of the largest ships in the Princess Cruises fleet, but it never really feels crowded. From the bustling three-story atrium to the variety of pools, bars, and restaurants, you'll be hard-pressed to see and do it all. The adults-only Sanctuary on Deck 17 comes at a price, but it’s well worth it to relax in the serene setting. Parents may never see their kids, who like to escape to their own separate sanctuaries. Dining venues include the traditional grand dining room, several casual spots, plus specialty options (for a fee), like the Crown Grill, focusing on steaks and seafood, and Sabatini’s, which offers Italian fare.
