A friend of mine tried to get me to stay with her at the Crescent, just for kicks. The plans ended up falling through, fine by me lol.
This article pretty much sums up the encounters. About half way down it discusses the paranormal activities, the first half is the history of the hotel.
The Crescent is kind of cool, but the entire town of Eureka Springs is really fun. Lots of shopping, great hippie restaurants, and very cool historic downtown architecture.
I've been there. They say its haunted...they have a tour daily that you can take. It supposedly an old mental hospital where they did crazy means of medicine. We stayed directly underneath one of the towers where TAPS stayed. Nothing crazy happened to us...but there were some strange cats there! It was eerie for sure. Rates are reasonable too.
