If you happen to recall their name it is possible to have them given a "kick tail" which is the Southwest method of tracking kudos for staff members.
Let us know here, or post to Facebook or Twitter and tag Southwest (SouthwestAir on Twitter).
Southwest when they see your post may ask you to message them privately with some details of your trip to track down the correct staff person.
Home airport MDW, frequent visitor to MCO to see the mouse.
