If you dress up as Lisa Marie Presley you'll have no problems to enter the rooms upstairs. But I'm afraight, you will only find empty rooms and some webcam filming out of Elvis' bedroom window. All the furniture is stored in a warehouse to preserve it in the best possible state. Visitors are not allowed upstairs. During the first years it's very likely that all the original furniure stayed where it was (at least, when they filmed "This Is Elvis" in 1981 it was in the original condition), but someday I guess they had to move the stuff out. Simply to preserve it. The stair construction doesn't hold so many people (over half a million each year), so the upstairs level of the house will never bee shown officially. But I believe they have filmed everything before they removed the furniture and re-decorated the living room. I can't imagine, that they threw everything out before documenting it properly. Maybe someday we'll see the films/photos. At least when "This Is Elvis" was shot they filmed a lot in the house and on the grounds (with this Elvis impersonator).
