I stayed at Rainforest Bungalow with my husband and our two children. Sadly, we were only able to stay one night--but wish we could've stayed longer. Our 9yo was in a state of bliss from the moment we stepped out of our rental car until the time we left the gate.
The bungalow was thoughtfully decorated to make you feel like you were at a nature retreat. And the kitchen (and cupboards) were well-stocked with everything you need to make a proper breakfast.
The coquí frogs were loud all night, but my husband and I were able to sleep right through their calls--and I'm a light sleeper!
We had a great stay, though far too short, and hope to make it back there someday.
