I've completely forgotten to book and now I can't find anything at all to pick from the south airport, arrival between Christmas and New Year for week. I'm going to the north with two kids so I really need one. I've tried all the online brokers and individual multinationals like Avis, Hertz and they've all said There is Nothing. Does anyone know of any smaller local ones I could try? Surely these places have cancellations from time to time, how can I tap into them? I would be so grateful for suggestions!
