You cannot go wrong with either operator... both are excellent. Chris Sawyer's group is more of a laid back, easy 'take a vacation and let us do the work' sort of deal. They carry your gear to the boat, set it up for you, help you into the water, lead a tour style dive, etc... I have never seen more given towards customer service from any other operation. The Blue Island group is every bit as professional, but much less hand holding. Kind of a 'take you out and dump you' sort of thing... which can be a good, depending upon the diver. You will see more/better wrecks with Blue Island than with Chris Sawyer because of the geographic location of the operators... most of the wrecks are on the south side, not the east side of the island. Based upon your previous statements, I would go with Blue Island if I were you... however, the Chris Sawyer operation is much closer to where you will be staying.
Water temps right now are are a frigid 77F, but will be a degree or two warmer by March/April. Nothing like bathtub temps of 84F to 86F we have in the summer, but not too bad either.
