Ecuador

In general, if you want to visit the Galapagos Islands, you have to be prepared to live on a boat while you sail around to see the region's incredible treasures—either a giant cruise ship, or a smaller yacht. Understandably, there's minimal infrastructure in this ecologically-imperiled region, which makes this environmentally-conscious arrival on Santa Cruz Island particularly special. Every day, you'll set out for naturalist-led excursions, either on Pikaia's yacht, or by land, and then return to the resort at night, where you'll find a pool, a spa, and a handful of restaurants to choose from. While the lodge invites kids ages 12-and-up, they'll likely make exceptions if you have a curious young one on your hands, as long as they're aware that the days are long (and start early). It's essentially akin to being on safari.
