I also just got new reservations for my car rental from Hertz as i had to add 2 more days instead of the plus 4 i had originally. With that in mind they just charged for another full week because with them you pay for 5 days and 2 days are free. My total came to $734.45 for 4 full weeks. Only $32.00 more than i originally booked. If I get bumped from my flight I still have car and condo till Saturday too. Pretty happy about that.
