Ever since my kids watched a TV show about Piranhas, they've been obsessed with the Amazon. “It's the biggest river in the world, full of scary fishes!” Sebastian told me one day. For any parent who's dreamed of traveling down this exotic waterway with family in tow, now is the perfect time to do it: Luxury cruise line Aqua Expeditions is offering free sailings on its ultra-luxe Aqua Amazon or Aria Amazon for kids under 12, through November 2014. Along the way, you'll spot sloths, caimans, pink dolphins (maybe a piranha), and more. It's the ultimate adventure for a family of wildlife lovers.
