When we think of luxury cruises, Peru isn't exactly the first place that comes to mind — but perhaps it should be. Aria Amazon River Cruises offers 3-, 4-, and 7-night cruises of the Amazon River aboard a luxury ship custom built by Peruvian architect Jordi Puig. The ship offers 16 oversized air-conditioned suites, each with outward-facing picture windows. For an even better view, head upstairs to the lounge, observation deck, and jacuzzi. And don't worry with your wallet, as you won't need it — all beverages are included in the price, as is gourmet Peruvian cuisine.
