Catherine Cruises is a cruise hotel in Halong that runs both room stays and tours of Halong Bay's islands and caves. A two-day, one-night itinerary includes a dinner course, buffet meals, and a balcony in each room, and a swimming pool is available. The ship has an elevator and follows the Hang Luon, Titop, and Song Sot routes, with kayaking, island walks, and cave visits. The routes match the day cruise, so a stay alone does not differ much from it.
