A 9:30 flight, is taking a BIG chance, unless everything goes perfectly.
IF the ship arrives on time, IF it's cleared on time, then you may possibly make it, but there are so many IF's.
You will get a letter in your cabin asking you to fill it out as to your disembarkation plans........fill it out and return it to the Front Desk immediately - don't put it in the drop box, but hand it to one of the Front Desk gals/guys. Your best bet is to take Express Luggage - you carry off your own luggage and are first off the ship.
The airport is only about 15 mins. from the port and there will be lots of taxis outside.
