We booked three nights at the jungle yurt. Unfortunately, we did not have a great experience and we only ended up staying one night. The main issue was the nighttime noise from the local coqui frogs. As numerous reviewers have mentioned, it can get a bit noisy at night. It sounds like this is usually not a big deal, but Captain Cook was experiencing torrential downpours while we were there and the frogs were out in perhaps greater force than usual. My partner and I both wore earplugs to bed but were both kept awake most of the night. Garrett was sympathetic and did provide a discount to partially cover some of our costs.
A couple other issues we did not anticipate: the yurt was very dark inside - the few lamps were inadequate to allow us to read inside in the evening. And there was no comfortable furniture we could lounge on. The couch and chair shown in one of the photos had been replaced by a daybed with no back support. Maybe this is not an issue if the weather is great and you are spending all of your time outside, but for us, given the rain, hanging out outside was not really an option.
The location definitely has its draws. The views are beautiful and any property with mango trees is a plus. The outdoor shower is awesome. But for us the jungle yurt was not what we had hoped.
