Scenic Jasper joined the fleet in 2015 with the largest panorama suites on Europe's waterways. The 169-passenger ship also has private balconies on 85 percent of its staterooms, plus a spa for those who want to indulge in a mani-pedi or massage while on board. The line added a new version of its Scenic Tailormade GPS to staterooms, providing dozens of pre-programmed walking and biking tours on a device the size of an iPhone — making it easier for passengers to explore on their own.
