The problem you face is that the rate for that property specifies "Us government on duty travel. Id-travel orders required at checkin limit 2 rooms per reservation - no groups.."

Most federal government travelers do not have "orders" or anything approaching them. If you truly do not have orders and accordingly cannot produce what you do not have, it is worth sending a complaint directly to Hilton and to the GM of the specific property.

At a location such as Norfolk, which is military-heavy, low level clericals may well have no idea that the vast majority of federal employees do not travel on "orders". The hyphen between "ID" and "travel orders" is poor form. Does it mean both or either?

I guess that the solution -- when you see something ambiguous -- is to clarify in advance.
