Hotel Registration

Our venue for 2018 SONC is the beautiful Rockville Hilton.  The Hilton is a modern atrium hotel in Rockville, MD with easy access to the entire Washington, DC region – perfect for a family vacation. The Rockville Hilton is 108 paces from the Washington, DC Metro providing access to downtown DC.  It also provides for transfer to/from Ronald Reagan/Washington National airport (DCA).  So if you fly into National, you will not strictly need a car.

We have negotiated an excellent rate for the Convention:


plus Taxes & Fees

You can arrive up to 5 days before the Convention and stay up to 3 days after the Convention at the Convention rate!

Even better, we have arranged for a block of rooms of various types, single bed, double bed and even some suites, all at the same price!  Book early to get the best choice.  Use this page to make your reservation.
