The Daily Mail is reporting that the guardsmen have hotel rooms, but that they are taking rest breaks during their 12 hour shifts at the Capital complex (inside before, in the garages, and now back indoors)
The whole situation seems overblown and ridiculous.
On the times I’ve stayed at a hotel in DC/Arlington....you are talking about a minimum of $240 a night. Would be hard to imagine renting out rooms for 21k National Guardsmen.
