In the past I've been an Avis / Europcar renter (price was the differentiation). Recently, I went with Hertz. On arrival in CPT, Hertz tried to hit me up for MORE THAN the full rental estimate and insisted on insurance coverage. Luckily, I had double booked (sorry, awaiting flame), I walked straight over to Avis and subject to a small rigamarole about vehicle choice (not vehicle availability), I was on my way.
