We stayed in the Treehouses everytime we went until we bought at OKW...It was a great option for us. IT had 3 bedrooms, 2 full baths, laundry and a full kitchen and livingroom.
2 bedrooms upstairs with the 2 baths, livingroom and kitchen. Laundry and 3rd bedroom in the base of the "tree"
I remember the downstairs bedroom's bed was hung on ropes and would swing.
We never really used the outside area of the treehouse because it was always dirty with "tree litter" and the peacocks would take over the balcony area. You'd wake up in the morning and they would all be snuggled up against the floor to celiling windows downstairs.
The area had a pool...it was a regular pool with an actual "deep end"!!
No restaurants, you had to go down the Disney Inst. for any services. Check in was at the Club Villas where Saratoga Springs is now being built.
