Touring Assistance for one trip

Hello - myself and family are going to Brittany on Friday by car, in previous years we have purchased Touring Assistance in case we have an accident whilst away but Touring only seem to offer an annual option and we were looking for a 'one trip only' as we generally only travel once a year. I have check europe assistance but their policy is €130 for our 11 day trip. Does anyone have an other suggestions please??
TIA
