Not sure we used the front desk as preferred customers

The trip we went on with Ocean Adventures - doing the pirate ship cruise with snorkeling along with touching sting rays and swimming with sharks - would meet your needs. The snorkeling is inside of a coral reef area and the waters were very calm. You went out with guides in groups of around 15 or so and they provided masks and fins along with passing out bread to attract the fish (of which there was a nice variety). We took kids that were 7 and 5 and they managed nicely on the trip - both snorkeling! Overall, it looked like most of their trips stayed inside the coral barrier - which would mean calmer waters but I'd make sure as there were offerings at our hotel where you could go out farther.

We also had a shuttle that was supplied by Ocean Adventures. It picked us up at our hotel. It was included in the fee. We had about a 20-25 minute ride as well. The length of the ride was due mostly to the fact that we stopped at about 3 other resorts to pick people up.
