TSandM:Just one word . . . You have to be sure and let Aldora know you want to dive the day you get in. I assumed from the website that that was a given, and they had to scramble a bit to get a boat together for us the first day. But they did it.
Yes, this applies to any operation. I don't know an operation on this island that won't take you diving the afternoon of arrival provided that: your flight arrives early enough, arrangements are made within enough time to get the boat together, and they have at least 3 or 4 people to send the boat out...so this is not something exclusive to Aldora by any means.
