We stayed in the Treehouses in the mid 80's. We loved it there and would go back, but we did have access to a Golf Cart for internal transportation and I think that would be an issue in the new world.
The original Treehouses were the largest accomodations on property at that time and a virtual pre-cursor to the Villas. They had 3 bedrooms (King, Queen and Double) and 2 full baths with a whirlpool in the Master. There was a full kitchen and eating area.They were the only accomodatations with a washer and dryer at that time. They also had a wonderful, peaceful setting with a nice round deck outside.
We loved our stay there.
