Aqua Expeditions is your chance to spend a few days on a boutique cruise that goes on an adventure through the dangerous surroundings of the Amazon. For a week long stay in a suite, prices will be around $7k---but that's a small price to pay for this kind of once-in-a-lifetime experience. More info here.
