Lately I have found that making a reservation on Travelocity rather than on the National web page results in SIGNIFICANTLY lower quoted rates. On a 1-way rental, I have done a 1-way rental WITHOUT a drop charge where it was several HUNDRED $ more on the National web site. Nor did they "correct" my rate when I actually rented and dropped. In fact, I do all my National reservations now on Travelocity because they consistently quote lower.
