It will all depend on when they are cleared to start letting people off. We did a self-disembarkation in March off an NCL ship (we are Canadian), and it went really fast. We left the ship at 8:30 and were at the airport by 9:15. The line for customs/immigration went really fast. As soon as you're through customs/immigration, porters are right there and quite determined to take your bags. It's not a bad idea to let them and they'll take you right to a waiting cab. Just have a few bucks for a tip and you'll be on your way in no time. The cab to the airport is a set rate of $24 or $25.00. Our flight wasn't until 12:30 so we had a bit of a wait at the airport. The dog was at the terminal as you leave to sniff your bags so as long as you didn't pack anything worth sniffing, you went right through.
