The Rooftop is such a great location for an alternative to inside the DC area. It is so big and open. It was a perfect location for a cocktail reception. The only thing is there is no contingency plan if the weather is bad. If there is bad weather, you have to move to a different location indoors. The indoors location is nice, but doesnt offer the same "wow" views and feel of the Rooftop itself. They have great rentals that are offered through the same company which makes things much easier and less vendors to deal with. Overall a great experience, even though you can never plan for the weather. My event ended up being indoors, so I couldnt take advantage of the vision I had of having a rooftop reception, but it was a GREAT party nonetheless!!
