Here is my two cents. This is probably the event: The NATaT Virtual Townhall: https://events.com/r/en_US/registration/natat-virtual-town-hall---march-1---5-2021-800942 Even though is states that it’s “virtual” , there is most likely an event going on for individuals to network and “schmooze” to lobby for $$. Even though the key speakers are lefties, if it’s a national town hall event, there will be some conservatives and they would most likely be on per diem (think of it as free expense account) which would mean they are not using their own money, so why not stay at my favorite president’s hotel right? This happens quite frequently in D.C. when major events roll through town or the “busy season” starts or even when Congress comes back in session. Per diem rates for government/state employees will change according to the “season” in D.C. which will allow them to stay at certain hotels, so they are able to get their work done when they go to D.C.
