A test of the OurBus website finds an available trip to New York City on Labor Day for $25.00. The departure stop is listed as the bus stop at the White Flint Metro station, on the northbound side of Rockville Pike, in front of the Metro station.
OurBus notes that buses will not always be branded "OurBus" (Worldwide Tours & Travel is listed as the charter company for next Monday's trip). The service offers passengers free WiFi, reclining seats, charging ports, free water, "sanitized" on-board restrooms, and no rescheduling fees. Tickets must be purchased online.
