Same here...
I made my Alamo reservation in March and redid them today. I saved $31 plus got upgraded one grade. As a side story, when I tried to use Travelocity to check prices it would not give the correct return time. Every time I put in 3:30 PM it came up as 3:30 AM. So my reservation was 12 hours shorter. I called them up and even though I told the non-intellegient life agent at LEAST 10 times not to cancel my old reservation she still did it! She said why not cancel the old one but didn't have an answer when I said maybe I need two cars. Then about the time she got a new reservation for me I finally got the web site to work and they were $15 cheaper than her price. Geeeez!
