We just returned a car on 11/11 to National at the Tampa airport. I too, did not realize that they were no longer in terminal, as we picked up our vehicle in Orlando. We were lucky enough to find a nice man (I believe he was with one of the competitors) to drive us to the National location. Thank heavens for him, because we would have never found it on our own. Make sure you have good directions so you don't run into the same problem. Once we arrived, the process took a few minutes, and the shuttle drove us back to the airport. But if you are not aware of this, you may panic a little like I did, but it all worked out.
