We just used ME this past week. We were picked up 3 hours prior to our flight time, and we were picked up right on time.
Our flight was scheduled for 2:30, we were picked up at 11:25 at the Allstar Music. We went right to the airport from the resort. By 12:30 we had checked in curbside with Southwest and went to the foodcourt for some lunch.
We were through security and at our gate by 1:30.
