My Girlfriend and I had a wonderful stay at the Parrot Nest. We weren't in the the treehouses but we had a cabin lower to the ground which was just as nice. The meals were delicious and everyone we met was fun to talk to. We both loved it!
Just some advice, if you go on a colder night, ask for extra blankets, or in our case, take the extra blankets from the spare bed. It can get chilly in the cabins. Regardless we were comfortable.
