Carole--do encourage them to look into driving to Miami. Depending on their schedules, they could think about driving down the night before and doing a hotel park and fly package in Miami, and their arrival day wouldn't be nearly so tiring. If they want to drive to Miami the same day, we have been using Park N Fly for several years. They do a great job of off airport parking, all valet, some undercover, and their shuttle service is excellent.
The only thing I would say regarding Orlando is that Frontier (yeah I know!!) does have one or two non-stops a week from Orlando. Unfortunately, if there is a problem with that flight, you could have a big problem. With AA, if something goes wrong, at least you should have a better ability to get there.
