I went to the Kennedy Center to see a popular Colombian artist perform a FREE concert on the Millennium Stage. We arrived quite early and stood in line, only to be trampled by people when they finally allowed everyone in. The Millennium Stage is basically in a hallway, with no seating, and is very cramped. It's nice that they offer these free, off-the-beaten path shows, and I did enjoy the music, but I wasn't impressed with their handling of the crowd, or the setup. The Center in general showcases a great variety of performers and offers reasonably-priced entertainment. I will visit again, but not the Millenium Stage.
