Here is what I posted on another thread about how it worked out for us:
We easily made a 10:45am flight out of MCO last Sunday. I was a bit worried about making the flight and normally wouldn't have booked that early but we wanted to be back home for something that afternoon.
It was just me & DH traveling so that made it easier than if we had the kids with us. Here is what we did:
-We packed in 2 small carryon suitcases so we wouldn't have to stand in line to check luggage at the airport
-We booked
DCL transfers to MCO
-We carried our luggage off the ship because I didn't want to have to take the time to locate it
-We lined up in the atrium at about 7:05 and were let off the ship about 7:20-ish
-Went through customs and we were sitting on the DCL bus by 7:30
-By 7:45 the bus was full and we were on our way to MCO
-Arrived at MCO at 8:30
-My FIL had checked us in online from home, so we just needed to print our boarding passes at the Southwest self serve kiosks (the actual line for checking luggage or full service for Southwest was HUGE!)
-Went through security (the line wasn't bad at all - everyone was still in the SW line, lol)
-We were at our gate by 8:55
We were lucky everything worked perfectly for us - I was worried because on the way to the port for the cruise the other side of the highway to MCO had a lot of construction and traffic was quite backed up.
Also, for breakfast went up to Cabanas around 6:30 - they had fruits and pastries out at this time - the full buffet did not open until 7, so we had some fruit and one last chocolate croissant there and ate again at the airport.
