Evening y'all. Will need a car in Glasgow (city centre) for a few days next month, and since it won't be over the weekend (when I usually go with Enterprise and their half price weekend rates) it will probably be with Hertz for a Focus or Mondeo sized vehicle.

I have a spare DC Silver upgrade voucher - is that likely to be the best deal I can avail myself of, or are there any other current CDPs or discount codes that would better it?

Thanks ^
