My boyfriend and I stayed at the dragonfly cabin for one night in February, it was booked beginning the next night, but we stayed on with Len (and KMEC) for the next four nights in the Mango Cabin (also fantastic). The dragonfly is wonderful, you are basically lying on a comfortable bed in the midst of the jungle, while remaining well isolated from the only part of the jungle that isn't awesome (bugs).

The amenities here also leave nothing to nothing to be desired, you have access to a full kitchen right nearby.

NOTE: I would recommend getting a vehicle for traveling around here if you've never been, we almost didn't and it woulda been a huge mistake. Tony's (search Yelp) is an awesome local alternative to expensive/boring airport car rentals.
