Hilton HHonors - need hampton inn discount ideas

Booked an award stay in August and now need another room at the Hampton Inn Corolla, N.C. (beach location).

This has to be the world's most expensive Hampton, weighing in at $261 a nite even with the AAA discount. Any ideas how I can stay there more cheaply?

They say they don't have anymore award availability and I'm Diamond!

As a Diamond, you were given one room using an award already.
