Cool. Just don't go making any calls to the Overlook Hotel. 
Nope. I did visit it a couple years ago while in Estes Park for a cousin's wedding.
That would be interesting. Even without the movie, I'm sure it's got all the creepy it needs.
Nah, that's just movie magic. It's not as remote or isolated as the movie made it look, and that was most of the creep factor. Just a stately old hotel. Maybe if you could be there all by yourself it would get creepy, but any large building would be creepy under those circumstances.
I used to work in an office building in Tucson that was once-upon-a-time the Pioneer Hotel. Used to be the place all the celebrities stayed when they came to Tucson to make westerns. In 1970 the place burned. A teenager was accused of arson for setting the fire and imprisoned for a couple of decades until the evidence got called into question and he was released last year. Anyway, when they turned the building into offices they simply walled off some of the burned areas, including the pool area, but they weren't particular about security in those days so tenants could get into all those areas, which some of us did in the wee hours one morning. THAT was spooky. Like, horror-movie spooky.
