Not too sure about all of July...but I tried all and every code I could find (via mousesavers etc.) and nothing worked, or nothing at least with a big $$ break. Then one day I just punched in my dates on Alamo.com "without any code" and got a mini-van for $199.00 for a week! So give that a try...hope this helps...My dates were late June till July 4th and it worked! But, I am flying into MCO, not Sanford..don't know if this makes a difference or not?!
Best of luck...Keep an eye on mousesavers, I'm sure more codes will be coming out soon! I hate this waiting game!
