If you have aircraft holding below and no EAT then I believe that you are in the situation of being told "delay not determined".
In that situation, you leave the airspace on the published route. Check out the local radio failure procedures.
Of course if VMC then simply continue VMC and land where you decide is best.
While I know you said the airfield does not have radar, a 7600 squawk will in many cases alert D+D who will contact the relevant ATC unit and let them know what is happening.
The one thing that I would not do in that situation is descend in the hold.
