Very new to scuba diving, but we are certified. We only have 3 days in Boracay and thinking of doing 2 dives in Boracay. A search shows are are 20 dive sites in the area, including a wreck sight. Which site would have the most marine life? Would love to see a shark, "nemo", eels? Also, we would prefer not to have to go more than 20 minutes out on a boat. Recommendations of PADI operators would be good too. I want a place where safety is key. Thank you!
