I remember those massive multi-floor hotels around Crystal City, and Northern Virginia is very large so there are tons of traditional highway-oriented chain hotels there.
Any status on whether MARC or VRE trains will be running? Certainly D.C. government liberals have no power over them, right? There are other options besides WMATA, especially Amtrak.
it doesn't matter if there are nearby alternatives, it's entirely appropriate to name and shame a dc hotel if you happened to book in dc and they decide to close down.
