We used Alamo at MCO last summer. I downloaded the app and used the skip the line feature. I did still have to use a self-check computer terminal (maybe that was unique to my reservation) and ironically there was a line for them because of how busy it was that day/time, but it was way quicker than having to check in at the counter with a human.

I'm amazed.
