Travelodge at Lutterworth is a good bet. Just off the M1, 15 mins from Brunty (depends on how fast you drive I suppose), The Elms pub is outside the front door of the Travelodge also - crawling distance.
BTW - if driving to Brunty in a 'low' car, watch out for the bumps on the road leading from the old A50 to the airfield - particularly after the S Bend. Too quick and you WILL bottom out.
