My wife and I were married at the Concourse and come back most years to celebrate our anniversary. Its' a terrific place for a large event and just as good for a weekend away. I'd recommend staying in the Governor's club. You get free top shelf drinks, free breakfast, free hor d'oeuvres at night, all in private bar on the top floor, with an exceptional view of the Capitol.
They also have a nice little pool/spa area and are located within walking distance from just about anything you could want to do downtown.
I know they did some renovations recently. All the rooms we've had have been updated and VERY comfortable.
Jodi (director of catering) was a true pleasure to work with for our wedding. She's extremely professional and on top of everything.
