There is no simple answer. Orlando can be a real pain, but if you are up front by the exit door and run, I have got through with my wife in 5 minutes. I have also taken 1 and 1/2 hours when stuck behind a queue of hundreds. Checking in, depends how busy the airport is and whether you are pulled out for special treatment or not. My best is approx 10 minutes and worst was over an hour. So expect the worse, hope for the best.
