Howdy, I'm another recent de-lurker, who decided it was time to plunge into the discussion. I'm sure we'll both be glad we did.
I stayed in one of the treehouse villas around 1999 or 2000, and it was incredible. If memory serves, upstairs, there were 2 bedrooms, 2 bathrooms, a living room and a small kitchen. Down a spiral staircase, in the "trunk" of the treehouse was another bedroom. I seem to recall an additional exterior door down there (keep it in mind if you have little ones).
I was traveling with a buddy, and it was a lot more room than we needed. We were both heavy snorers, and neither of us ever heard the other.
The area around the treehouse was very quiet and tranquil (there are other parts of the resort that get a considerable amount of DTD noise). I recall the bus stop being quite convenient to our treehouse, but fior the life of me, I've no idea which treehouse we had. It's sad getting old.
Anyhow, if you have any questions, I'll do my best to answer them.
