Only speculation on my part - because of their location, the op will only go to the few sites that are on the NE side of island. Creole Rock is shown as a dive site there - I've snorkeled around it before as it is a popular snorkel spot - don't think it's very deep.
The majority of dive sites around the island run along the south side of the island. That said, I've only dove along the south side (some decent wrecks, sharks, etc...) The few sites on the NE side may be great. Also the convenience of how close the op is shouldn't be overlooked. Hopefully someone with experience on the north side will chime in.
