Just returned from a 6 day stay there, my second trip in a year. I agree with the prior recommendations to go with Unexso. They run a little bit higher in price than some of their competitors, ($100 for 2 tank) but they are a very professional, friendly, and knowledgeable team. They have lockers you can use for free to stow your gear overnight, which is really convenient for multi-day diving with them (bring a lock, but it’s safe. Have left my gear overnight, without a lock, never a problem. If you dive three days or more, there’s a discount on the total price of diving). There’s a big rinse tank just outside of the locker room, and hot showers steps away. There’s also a nice restaurant adjacent to the dive center.
For wrecks, Sea Star is good and no penetration. Theo’s, of course, but they couldn’t find the buoy when we went out last week. (rough seas, one sick crew member). Picasso’s Gallery is gorgeous, lots of juveniles, as well as Moray Mana. Poppa Doc’s has a small wreck, lots of friendly sharks, and scattered coral heads. Enjoy! I love it over there; the friendliest people, great diving and gorgeous beaches. (I stayed at Island Seas resort, on the beach and a five minute ride from Unexso, with free shuttles. Had a Living Social coupon for 4 nights for $250, and included a $50 food and beverage credit. February is likely the busiest month of the year there.)
