The Sliding Dome Cover on Holland America Line ships is a unique feature that sets them apart from other cruise lines. This impressive structure covers the main Lido Pool area and is made of retractable glass panels, creating a versatile space that can be used in any type of weather. Passengers can relax and swim in the pool, surrounded by natural light and fresh air when the dome is open on sunny days. On colder or rainy days, the dome can be easily closed to maintain a comfortable temperature within the pool area. This feature is especially useful for cruises with diverse itineraries, as the Sliding Dome Cover allows for year-round enjoyment of the pool area, no matter the destination or weather conditions. Whether you're cruising to a warm Caribbean destination or exploring the unique landscapes of Alaska, the Sliding Dome Cover on your ship ensures that guests can make the most of their time on board.
