Hi fishman, I had a Philippines vacation during last May with my family and visited both Ocean Park & Mactan Island aquarium. we really enjoyed the underwater tour of Philippines. The Mactan Island aquarium is similar to
Manila Ocean Park, but little smaller. Visiting Ocena park & the Mactan Island aquarium is an exciting experience, we visited Ocean park first and came to Cebu. It's a fully guided tour and we got an opportuinity to see the angelfish, octopus, cowfish, shark, sea horses and cowfish with with horns. Even we touched the starfish, crab and other sea creatures with the help of our guide. You too get a chance and hope you will enjoy too. Cebu is the second largest city after Manila and offer many interesting places, so have a nice time at Cibu. And some other interesting places that you can visit during your
Philippines vacation are
Banaue Rice Terraces and the
Boracay Island, best of luck!
