You will not be able to take it on board, but you will be allowed to gate check it. When you check in at the gate, ask for a gate check tag. Then take the stroller down the jet way, fold it up, and leave it just off to the side of the very end of the jetway by the plane door.
When you land in Orlando, it will be either just inside the jetway like where you left it at your departure, or at the end of the jetway, just inside the terminal.
Same thing with wheelchairs. Sorry, you can't gate check your kids or your mother-in-law.
