You're in my city! It's so nice seeing people have a good time using DC public transportation. I've seen my fair share of mishaps and delays on Metro many times, but overall, I think it's a much more enjoyable public transportation system than most places. Hope you enjoyed DC!
Unfortunately its looks like the Circulator won't be around for much longer because of budget issues.The loss of tax revenue as the result of so many empty downtown office buildings post Covid has been rough.
Nice tips. But in general I found hotels in Washington way too expensive. With little parking in the national mall area, you had to rely on public transit and spent too much time walking.
