After everyone's great advice, and exploring flights and hotels, my wife and I have decided to go to Turks & Caicos next week. We are staying on Provo. What can everyone tell me about a dive operator called Big Blue Unlimited? I know lots of folks like Caicos Adventures. How do the two compare? Remember, we are very much beginners, and are in fact completing our certification on this trip with the required open water dives. Thanks!
