Definitely is always subject to change (when we went, we did the 3 house tour, and it turns out for that day the afternoon tour was only doing 5 houses), but my friend and I did the 10:30, 3 house tour and hit Carnival Graveyard, Scary Tales, and ended with Stranger Things.
Photo policy was different for each house, but we had free reign in the first 3 or 4 rooms of Carnival, then toward the middle we were asked not to photograph two or three rooms, before we had full reign again.
Scary Tales they only allowed the facade, and then Toupee.
Stranger Things we could only photograph Mirkwood and the Lab.
Hope this helps, but it seemed like for us it was a Soundstage only tour!
