New points system seems very vague. I just spoke with an Avis representative who told me I needed 1800 points for a one day rental. Now I read here that you can get a 4 day minivan rental for 300 points. How does that work. Why can't Avis give us a chart that says exactly what the points are worth. If I need 1800 for a one day rental then this NEW program is a joke!,
