You 'might' make it. If you are ready to get off that ship as soon as possible, and have a car service car waiting for you at the ship, you should be able to be on your way by 7:30...an hour or so to MCO, it's now 8:30. A bit tight, but as long as you're there by 8:45, you 'should' be okay. Of course, that isn't 100%. Not sure if you want to take that chance. I wouldn't. That will be the time there is a massive accident on the road and you get held up for 20 mins, and then there will be a huge line at security.
I would try to change the flight to one after noon..that's the earliest most like to book a flight home at.
