<p>juniebug - Yes, Home Ride drops off at the Vienna metro station. We did look into the Metro and Amtrak from Vienna as an option for coming home. Getting to Philly would require a few transfers: metro orange route from Vienna to the the Metro Station; red route to Union Station; Amtrak to 30th St Station in Philly. Seems like a lot of bouncing around and not incredibly practical, but if there are no other alternatives, it could serve as a back-up plan. </p>
<p>I agree that getting back to campus this way would be extremely risky with potential delays, unless you start out with a fairly comfortable time cushion built in to your plan.</p>
