Hi Anna,
When Lisa and I were in the Turks before we did not travel with Oliva and we stayed and the Sands at Grace Bay. It was wonderful, however I am looking forwad to another Oivia experience. We chose Caicos adventures based on their reputation and all the recommedations I received. They were excellent. The boat was never crowded. They were very safe. You can choose to dive with a guide or on your own if you are comfortable with that. We chose to go with a guide and I cannot complain one bit. They were great. Pointed out everything.
In addition, Caicos adventures kept our gear for us, washed and rinsed it and then also set it all back up for us the next day. All we had to do was get on and off the bus.
I think most of the club meds have a dive club, but they are all pretty conservative and do not take you necessarily to the best dive sites.
I dove with Club med in Columbus Isle. I found them to be equally safe, however the guides were very conservative and we did not get to see quite as much.
I am not sure if they pick up at Club med or not, that is something I have to find out still.
Since we will be there for two weeks we will probably try out the Club med dive shop to see how they are.
