This treehouse is amazing. I have never stayed anywhere quite like it. There's a short walk on a nice trail (a little over a 1/4 mile or so) from where you park, but rather than being an inconvenience it helps to set the mood. Mary Jane was very nice and very welcoming and the treehouse is super cool.
Its a little small for a hotel room, but huge for a treehouse. Its has all the amenities one can ask for including a stove/oven, refrigerator, TV and shower. The bonuses include an very nice little hot tub and a friendly cat that hangs out in and around the the treehouse.
The only thing I can say negatively about the place is that its closer to other building/residences than I would have thought. However, all in all it was a fantastic experience, ridiculously romantic and I highly recommend it as a bday or anniversary surprise.
