There is a really good special for a rental car with Budget through Southwest. Just enter U072722 in the corporate code box (pick up rental car by 12/13/07). It came to $156. total with taxes and fees for 12/8 - 12/15 midsize (7 day rental). That's the best deal I have found so far. BUT, I know nothing about Budget and didn't book it. I love National for Emerald Aisle and Alamo with QS. But maybe this can help someone else.
