| Artisan Chauffeur & Concierge Montgomery County car service | Emailed quote by route, pickup point, vehicle class, wait policy, luggage, and pass-through terms. | Pre-arranged BWI, DCA, and IAD transfers, NIH and Walter Reed visit days, I-270 campus schedules, families, delegations, SUVs, and Sprinters. | Higher cost floor than Metro, taxi, or standard app service. |
|---|
| Metrorail and regional rail | Published transit and rail fares plus station-access and final-mile costs. | Solo light-luggage trips when the station and schedule fit; DCA has a Metrorail station on the Blue and Yellow lines, and BWI connects to Washington Union Station by Amtrak and MARC via a free rail-station shuttle. | Not door-to-door; weaker for luggage, families, campus visit days, early international departures, and multi-stop schedules. |
|---|
| Taxi or standard ride-app | Metered, app-based, or dynamic pricing. | Simple on-demand trips with light luggage and flexible pickup timing. | Vehicle fit, pickup point, final cost, wait handling, and gate-entrance coordination can vary. |
|---|
| Hotel or shared shuttle | Provider-specific scheduled service. | Passengers whose provider schedule, route, and luggage rules fit. | Less control over pickup time, vehicle class, route, and private handoff. |
|---|
| Rental car | Daily rate plus fuel, tolls, parking, and time cost. | Travelers who need a personal vehicle across a multi-day county stay. | Adds I-270 peak congestion, ICC tolls, campus-parking, and garage friction. |
