Aqua Expeditions, one of the two high-end cruise companies plying the Peruvian Amazon, just launched its second boat, the Aria. There are only 16 suites, each with panoramic views, as well as an elegant restaurant and a sun deck with a Jacuzzi, making it tempting to stay up top, sipping pisco sours as the jungle hums by. From $2,550 for three nights; aquaexpeditions.com.
