I have access to Costco so I can get burgers if needed.
Also, for those out-of-towners, the U.S. Space and Rocket Center is definitely worth checking out while you are in Huntsville. I would recommend staying an extra day and go to the Rocket Center on Sunday. Here is the website:
U.S. Space & Rocket Center | U.S. Space & Rocket Center Admission is suppose to be $20 but at the bottom of the "Hours & Prices" page there is some sort of ASTC Travel passport program for free admission..... This is the first I have seen or heard of it so I will try to call and get more information.
