AKR will pick you up from the airport and handle all of your baggage for you once you pick it up from the belt. They will take them to customs and deliver them to your room.
The bus is air conditioned and you will get to see a bit of the island on the way to the resort.
Sherri (the lady pictured) will even give you a little tour on your way from the airport. She is an awesome lady and one of the happiest people I have ever had the pleasure of meeting.
Getting to and from the key and to the main island of Roatan is easy. Just bang the dive tank hanging on the dock and the water taxi will be there to pick you up. The trip will take about 60 seconds to the main island. You can ask to be droped off at the Baileys key so you can snorkel with the dolphins, it takes about 120 seconds to get to Baileys Key.
The last taxi is at 2200 hrs (10pm), the guards will take you after that but they are not the best boat drivers.
