No stories. I grew up a couple of miles from that hotel up Rt. 1, so I never had any reason to stay there. I know I went to the restaurant in the place once or twice, but I don't recall any distinguishing features or events.
Until that section of Eisenhower Valley built up, the hotel sat more or less by itself off the beltway for years. And it had that ridiculous sign advertising "Washington's Only Skyscraper", which didn't refer to the hotel but some building the developer, Dutch Hoffman, wanted to build. Even as kids we laughed about the "idiot who built that place all by itself on Telegraph".
The guy must have been a real visionary though, or really lucky, because I think he bought the land before the Army Corp of Engineers put the flood controls on Cameron Run and definitely before the Yellow Line had a Metro stop there.
Here's one thing the OP might find interesting. The developer, Hubert Hoffman, has his eternal resting place on the property. The local color guy for the Washington Post did a story on it in 2006,
