Hidden treasure in DC. We went earlier in the day and beat the crowds. Staff were engaging and helpful. A return visit is already on my list!!

When in DC, y'all should make the time to search for the secret doors at the Mansion on O Street! It's great fun! Rainy day or not, be sure to visit!The history is cool; Rosa Park lived there for years! There's a John Lennon room & a log cabin room. You can actually stay there too.The events look like great fun; meetings, retreats, weddings and New Year's Eve parties...Parking can be a bit tricky so it's best to take a metro to Dupont Circle and walk from there.
