Everyone will disagree with me on this, LOL.
I don't think it should have been opened to the public. Every single thing about Elvis is now public knowledge - from his bathing habits to his bowel movements to his sex life. I don't think his home should have become public property, too.
I see why Priscilla and the other trustees decided to open it, though - it's provided a pile of money for Lisa.
But I don't care about that. Lisa could have made do with a million or two - or could have worked for a living, like the rest of us.
