To request lodging/housing hosted by local singers, contact Corinne Ducey at 240-462-0543 and leave a voice message. If no response, email her at corinne [dot] ducey [at] gmail [dot] com. Contact her as soon as possible, because the demand may exceed the number of available rooms. Be sure to mention any requirements with respect to allergies, smoking, pets, etc.
There is no official hotel for the convention. The organizing committee may recommend one or two hotels.
