Drive to a Metro station that has multi day parking availability. Take the metro downtown to your hotel.

Idk what “across the highway means” as far as walking goes… you couldn’t cross a highway on foot. Pick your hotel, read reviews, stay downtown, then metro everywhere. Or Uber/walk/bike/scooter/crawl. Up to you!

Multi-day Parking Multi-day parking (also known as overnight or long-term parking) is available at four stations: Greenbelt, Huntington, Franconia-Springfield, and Wiehle-Reston East. Each of these stations has between 15 and 17 spaces allocated for multi-day use of up to 10 days. Availability is on a first-come, first-served basis. There is no charge for multi-day parking beyond the regular fee. See the individual station pages for more details about multi-day parking at these four stations:
