Regan National is right on the Metro. Baltimore is closer in miles and easier to get to by car. There is a train that will take you to Union Station and then the metro to Silver Spring.

If you come in to Baltimore on Wednesday, I can probably come get you. You could stay with me, but I'll be crazed. Thursday is hell. You can also take a cab from BWI to the con for around $50.

Don't come into Dulles.
