Most luxury boat rentals have five or six staterooms or cabins in various configurations, including twins, double, queen, and king beds. On most charter yachts, you can customize the configuration of the cabins dependent on the number of guests. This will allow you to take between six and 12 charter guests. Depending on the charter vessel, staterooms may include ensuite bathrooms, state-of-the-art entertainment systems, private study areas, and walk-in wardrobes. Larger mega yachts may have additional cabins for staff members like nannies, security, or personal butlers.
