Decided to go with Admiralty in St John..due to the fact they do pick ups, so no need to rush in a cab to try to catch the 8:30 morning dive.
As for St Martin, nobody could gurantee we can dive Moonhole, and we found some places had a single tank shark dive, so initially we tried to squeeze a morning 2 tank and an afternoon shark dive, but then we settled with with Ocean Explorer, whom offered 2 tank dive with a 2nd dive being a shark dive. This is even though they are a bay away and we needed to take an cab there. Their 2 tank dive also starts at 11AM, so there is no rush to get to the dive shop if we did a morning dive or back to the cruise ship if we did an afternoon dive. It is pricey though. A bit more than the shark dive in Bahamas w/Stuart Cove. But we need to make up for the lack of sharks in our galapagos trip (although this is a bit of a cheap thrill dive vs the natural "safari" dive of galapagos).
