You have a really, really tight time frame there. If everything goes perfect for you (debarkation starts on time, there are no accidents, no line at customs, no horrendous security line at the airport, ect) you may make the flight. But I have been on cruises that didn't start debarkation until almost 10am because of customs and billing issues with passengers. The Orlando airport is also known for long lines at the security screening area.
If you can change your flight to a later one so you will not be stressed about making it to the airport with a whole lot of factors out of your control.
