Crown Princess may carry more than 3,000 guests, but it never really feels crowded. A popular vessel in the Princess Cruises fleet since 2006, this ship features a bustling three-story atrium and a wide array of pools (there are four, plus a splash pool), nine bars, and eight restaurants. The adults-only Sanctuary on Deck 17 requires a fee, but it’s well worth it to relax in the serene setting. Meanwhile, kids and teens can escape to their own separate sanctuaries at Camp Discovery. Dining venues include the traditional grand dining room, several casual spots, plus specialty options (for a fee), such as Crown Grill for steaks and seafood, Sabatini’s Italian Trattoria for authentic Italian cuisine, and The Salty Dog Gastropub for gourmet burgers and pub fare.
