Four luxurious cottages are spread across this exclusive campus that winds through botanical gardens and out to a secluded cove. Vaulted ceilings and screened-in patios with ocean views help give the rentals a rustic yet high-end feel. The Bamboo, Mango, and Dolphin houses have two bedrooms and two baths, and the Cabana has a single queen-size bed for couples.The property has a private dock and gazebo that overlook the dolphin pen at Anthony's Key Resort. At night, you can hear the dolphins splash around as phosphorescence glitters in the water. Rentals are by the week.
