I can tell you that as an area resident and someone who works in professional services (and knows a lot of other folks who do), the switch is being flipped pretty quickly around here. Traffic levels and office attendance are way up, and a lot of firms are setting return to “new normal” dates, including regular client travel, for after thanksgiving.

Btw, hotels like Conrad and WA would never have had a largely true government clientele. Perhaps they would offer a very few rooms at GSA rates. But the main clients would be professional services, tech, etc. Now of course those people are largely serving govt so your point holds to some extent, though much less than it used to as the economy of the region has diversified quite a bit.
