Are the tree houses at Saratoga Springs accessible?

I think you mean if they are accessible for mobility impaired. Yes, they have some units that are equipped with ramps and I am assuming accessible interiors. They are not all this way but there are a handful. Just stayed there last week and enjoyed our stay.

They are a few that are handicap accessible. My family stayed in one last week and had a great time. The shower in the main room is roll in and services helped us get a toilet chair attached. Very accommodating.

Just stayed there last week and had a great time. This was my second stay there and highly recommend. As far as reservation it could be hard getting your exact dates but worth a try.

If you mean are they now rentable the answer is yes. As for being accessible, they would have to be otherwise guests could not get to them. (That was a joke Cathleen.) They go quickly and our rented out very far in advance so if you want to try to get one I would suggest that you call Disney now!
