One of a pair of third-generation Space-Ships from Scenic — river cruise ships that combine generously sized cabins and public areas with futuristic amenities — 169-passenger Scenic Opal offers all-inclusive luxury as it plies Europe's waterways. Just like with its sibling, Scenic Jasper, Scenic Opal guests can listen to personal GPS-guided commentary devices while relaxing on the Sun Deck (or soaking in the vitality pool) as they watch the world go by. Another soothing spot is the all-weather sun lounge found in most staterooms; with the push of a button, a picture window rises on the balcony to let passengers enjoy the view even when it’s cold or rainy.
