As we ascended the ramp, we stopped off at each annex side room, which made our experience of the Rotunda disjointed. In retrospect, I'd recommended viewing the rotunda exhibit seamlessly as you climb, and then visiting the side rooms on your way back down.
Overall, the view from the top was mesmerizing—and the parallel lines captivating. From there, you are able to see an overview of the main exhibition—on our visit it was Christopher Wool. The monochromatic-ness of Wool's work was quite striking when paired with the lines of the Guggenheim's architecture.
The museum as a whole seemed small, and without the added interest of the ramp and the spiraling gallery, it would be underwhelming. It had some structural elements that seemed to interrupt the building flow, bathrooms that intruded and you had to walk around instead of passing seamlessly by.
But for any Frank Lloyd Wright fan, it's an interesting and important piece of history.
