We've arranged for a block of rooms at The Hotel Roanoke & Conference Center (110 Shenandoah Avenue, Roanoke, VA 24016). The block rate is $139/nt.
This rate includes double king and queen rooms if you plan on rooming with a fellow Institute attendee. This is a courtesy block, so book as soon as possible to ensure you receive the special rate (and select "attendee" as your guest type).
The Hotel Roanoke is just a couple minute walk from the Roanoke Higher Education Center where morning lectures will be held, so there's no need for a car when you're attending the Institute!
