An almost overwhelmingly stunning first-impression of DC. Our guide Kate was warm, a clear communicator and guide, and very informative. Each destination we saw was worthwhile and gorgeous, lit-up at night. I was lucky to have gotten onto our tour bus early, however. Considering how many stops are taken, I can imagine the process of waiting to step out from a far-back seat being tedious, but I can't speak to that experience. That said, I'd recommend it to any other first-timers to the city. It perfectly set the tone for the rest of my stay there.
